Can Humans Live On Any Other Planets One Day?

For our project we studied the planets in our solar system. We looked at the temperature, air quality and surface of each planet to see if humans could live on one of the planets one day.  We used many websites as well as books to get our information.


We wanted to know if we could live on any of the planets, moons or stars.

We decided to do this topic because we are very interested in the planets and space. 

We already knew that we could possibly live on Mars one day.

We already knew that some of the planets were not safe to live on because of their extreme temperatures and because of their toxic air.

We are hoping to learn more about  the planets and see if they could support life.


We used the internet and books to research information about all of the planets.  You can find a link to our entire project in the attachment section.  As well, you can view a video of our presentation in the presentation section.



Mercury is the closest planet to the sun. Mercury is the smallest planet in the solar system. It is just a little bit bigger than the moon. Mercury is the fastest planet that moves around the sun. It takes mercury 88 earth days to go around the sun. Mercury was discovered in 265 BC. Mercury was discovered by Timocharis. In the daytime, Mercury it is 427 degrees celsius and 800 degrees fahrenheit. In the night time on mercury it is -180 degrees celsius and -290 degrees fahrenheit. NASA sent a spacecraft to mercury to take pictures of it. Nobody has ever been to Mercury because it is too hot and it is toxic from pollution. This pollution causes acid rain. We would not be able to live on mercury because of this.



Venus is the second planet from the sun. Venus was discovered in 1610 by Galileo Galilei. When Galileo Galilei was looking at Venus through a telescope he realized that Venus has phases just like the moon. People call Venus Earth’s sister planet because they are very similar in size. It is believed that there was once life on Venus just like the life we have here on Earth. The average temperature on Venus is 462 degrees celsius and 864 degrees fahrenheit. Venus is the second brightest planet in the sky. Venus is sometimes called the morning star and the evening star. Venus is the hottest planet in the solar system. Venus is too hot to live on.



Earth, the only planet in our solar system that sustains life. Unlike all of the other planets, Earth is not named after a Roman God, it comes from the Old English word eorthe. Earth is the 3rd planet from the sun. You may think that our Earth is in the right position for it not to burn, but that is not the case. Before the time of humans, Earth was just like Venus. Earth had nothing but lava. Before there was no atmosphere on Earth. When asteroids collide with Earth, it made steam. The steam turned into water vapor, and the water vapor made lakes, oceans and rivers. The water then created our atmosphere. Because of the water the sun can’t burn Earth. The atmosphere on Earth has safe gases for us to breathe in. Sometimes you might hear that Earth has a twin. Earth doesn’t really have a twin, but Venus is almost exactly the same size as Earth. Venus is often referred to as Earth’s twin. Our planet is the 5th largest planet in the solar system. The temperature on Earth can be between -25 degrees celsius to 45 degrees celsius. We can 100% live on Earth.



Mars is the 4th planet from the sun. Mars was discovered in 1610 by Galileo Galilei. Mars was named after the ancient Roman god of war. Mars is made up of silicon, oxygen, iron and magnesium. Mars has enough oxygen for us to breathe. The atmosphere is about 100 times thinner than Earth. 95 percent of the atmosphere is made up of carbon dioxide, and 2.7 percent is nitrogen. The average temperature is about -80 degrees fahrenheit or -60 degrees celsius. In winter Mars can reach -195 degrees fahrenheit or -125 degrees celsius. Mars can get up to 70 degrees fahrenheit or 20 degrees celsius in the summer. It is not very windy on Mars. The fastest wind speed has been 100 kilometers per hour. One day we might be able to live on Mars, but it would take a long time to figure out how to get life on Mars. The soil is not good for plants and it is too dry for us to live on Mars today. One day we might be able live on Mars.

Perseverance Rover On Mars

On July 30, 2020 a Rover was sent to Mars by the NASA Space Station. 

It took 7 months for the Rover to reach Mars. The Rover landed on Mars on February 18, 2021. 

The Rover is called Perseverance Rover. 

Perseverance will stay on Mars for 1 Mars year, which is 687 Earth days. 

The Perseverance Rover is about the size of a small SUV. 

The NASA Scientists landing the Perseverance Rover are looking for an ancient lake called Jezero Crater. Scientists think this Crater held water in it a very long time ago. They believe this is the best place to look on Mars for signs of ancient microbial life. 

The Scientists will also collect samples to return to Earth. 

Perseverance Rover will be testing for future human exploration to Mars.

 Jupiter was discovered in 1610 by Galileo Galilei. Jupiter, also known as the gas giant, is the 5th planet from the sun. Jupiter is known as the gas giant because it is made of the gases hydrogen and helium just like the sun. Jupiter is also the biggest planet in the solar system. On Jupiter there is a spot called the Great Red Spot. This spot is a storm in the southern hemisphere of Jupiter that has been going on for 150 years! We would not be able to live on Jupiter because there are so many storms and it is way too windy. You would also not be able to breathe because of the gases hydrogen and helium. Just like the sun and saturn's gases, both of these gases are really deadly.  We can not live on Jupiter.



 The sun is not a planet, it is a star. Here is some information about the sun. Saturn is the 6th planet from the sun. Saturn was discovered in 1610 by an Italian astronomer named Galileo Galilei. He discovered Saturn by looking through a telescope. Saturn was named after the god of all titans, Kronos. Saturn has many rings made of billions of rocks and ice. The rocks and ice can get as small as a grain of salt and as big as a house. Saturn's rings are not solid so you can’t stand on the rings of Saturn.  Saturn has 60 known moons. Saturn has no surface so you can’t stand on it. Saturn is made out of hydrogen and helium. If we breathe hydrogen we can get dizzy, have headaches, vomit and even go unconscious. Breathing helium can be seriously deadly as it can block your blood vessels. Saturn has no oxygen. Saturn can be as cold to -288 degrees fahrenheit or -178 degrees celsius. Saturn is very windy. The wind speed can get up to 1,800 kilometers per hour or 1,118 miles per hour. The fastest wind speed on earth was only 400 kilometers per hour. There is no life on Saturn because there is no solid surface. We could not live on Saturn because of the surface and the air.  We could not live on Saturn.



Uranus is the 7th planet from the sun.Uranus was discovered on March 13, 1781 by William Herschel. Uranus was named after the ancient god of the sky. Uranus is made up of water, methane and ammonia fluids. The methane is the reason that Uranus is blue. The atmosphere in Uranus is very thick with hydrogen and methane. Both of them are very flammable, and therefore toxic if breathed in. Uranus has 27 known moons. The temperature on Uranus is -353 degrees fahrenheit or -213 degrees celsius. There are strong winds on Uranus. Uranus is off its axis by 98 degrees. Uranus is titled because a rock the size of earth hit Uranus during its formation. Uranus has 13 rings. The rings are made out of water and ice. There is no source of life on Uranus. Uranus would be too cold and we would not be able to breathe. We can not live on Uranus.



Neptune is the 8th planet from the sun. Neptune is cold, dark and windy. Neptune was discovered in 1846 by John Couch Adams, Johann Gottfried, Galle and Urbain Le Verrier. Neptune is blue like Uranus. Neptune’s surface is almost like Earth’s surface. The average temperature of Neptune is -20o degrees celsius and -392 degrees fahrenheit. Neptune is the coldest planet in our whole solar system. Neptune has five rings around it. Neptune is blue because its atmosphere is made of hydrogen, helium and methane. Methane is mainly what gives neptune its blue colour. This happens because methane gases absorb red light and reflect blue light outwards. Neptune is a gas giant so there is no solid surface for us to land on. Neptune is also very cold and there is not very much oxygen or water. This means we can not live of neptune. 



Pluto is the 9th planet from the sun. Pluto was first discovered on February 18th, 1930 by the Lowell Observatory. Pluto was named after the Roman god of the underworld, Hades. Pluto has 5 known moons. Pluto is a lot smaller than earth. If earth was the size of a nickel than pluto would be the size of a popcorn kernel. Pluto is about 3.7 billion miles away from the sun or 39 astronomical units away. Pluto is not considered a planet because it is not in the rotation of the solar system and it is too small. The temperature on Pluto is super cold. It can get to as cold as -226 to -240 degrees celsius or -375 to -400 degrees fahrenheit. Pluto has a very thin atmosphere. Pluto is too cold to have life on it. Pluto has a frost coat surface made of methane and nitrogen. Breathing nitrogen can be deadly. That is because nitrogen gets rid of the oxygen in the lungs. Methane also reduces the oxygen we breathe. Therefore, we will never live on Pluto.


The Sun

The sun was discovered in 450 BC by Galileo Galilei. The sun was made 4.5 billion years ago. The sun was made from a giant swirling cloud of gas, as well as dust. It is called a solar nebula. The sun is made up of hydrogen and helium gases. Hydrogen gives you headaches and makes you dizzy and helium can be very deadly. The sun has the same gases as Saturn and Jupiter. The sun is 5505 degrees celsius, 9941 degrees fahrenheit! The sun is a star called the yellow dwarf star. Nobody has ever gone to the sun because it is way too hot! NASA’s solar probe spacecraft will be the first ever mission to touch the sun. NASA is going to send the spacecraft into the sun’s atmosphere about 4 million miles from the sun’s surface. As you can see the sun is extremely hot. Plants, animals and humans would not be able to live on the sun because of its hot temperatures. That shows that nothing can live on the sun. Although, without the sun we wouldn’t have plants because the sun is what makes plants grow. Without the sun it would be impossible to live on Earth. Humans could not live on the Sun.



The moon is not a Planet, it is a satellite, here is some information on the moon. The moon was discovered in 1610 by Galileo Galilei. The moon is a natural satellite that orbits the Earth. The moon takes 27 days to orbit the Earth. The moon has 8 phases. The first phase is the New Moon and in this phase you can’t see the moon at all. The next phase is the Waxing Crescent and you can only see a tiny sliver of the moon on the right side. The third phase is the First Quarter. In the First Quarter you see half of the moon on the right side. The next phase is the Waxing Gibbous. In the Waxing Gibbous phase you see three quarters of the moon on the right side, so the moon is almost full. The next phase is the Full Moon! In this phase you see the entire moon! The phase after the Full Moon is the Waning Gibbous. In the Waning Gibbous phase you will see three quarters of the moon but it is lit up on the left side of the moon. This means the moon is starting to get smaller. The next phase is the Third Quarter or Last Quarter. In this phase half of the moon is lit up on the left side. The last phase is the Waning Crescent. In the Waning Crescent phase you can see a tiny sliver of the moon on the left side. Waxing means growing and waning means shrinking. Gibbous means that the moon is almost full. These are the moon’s phases in the northern hemisphere. In the southern hemisphere the moon’s phases are the opposite. The moon finishes all its phases in a month. The word month came from the word moon. The moon has little and big holes all around it that are called craters. These craters were created by meteorites. The moon is the only place in our solar system that people have set foot on. The moon is what creates tides in our oceans. The tides are because of the moon’s gravitational pull. When it is day time the moon is 127 degrees celsius and  260 degrees fahrenheit. When it is night time the moon is -173 degrees celsius and -280 degrees fahrenheit. Someday we may be able to live on the moon because the moon’s gravity isn’t very extreme, but to live on the moon we would need some sort of water source. Humans can not live on the moon.


Fun Facts About The Planets

All the gas giants have rings!

The brightest planets in the sky are Mercury, Venus, Mars, Jupiter and Saturn!

China and Dubai sent missions into space and those missions made it to Mars!

The mission that NASA sent to Mars landed on Mars at 2:15pm on February 17, 2021!

A day in Venus is 244 Earth days. That means a day in Venus is almost a Earth year!

The craters on Mercury are named for artists, writers and composers such as Renoir, Bronte and Beethoven.

When Mars is closest to the Sun and it’s temperature is at its hottest, the wind speed is at its fastest and the entire planet is sometimes covered in a dust storm.

Saturn has the lowest density of all the planets. Saturn would float in water if you could find a sea big enough to hold it.

The space probe Voyager 2 flew to Uranus, and then they used Uranus’s gravity to fling itself to Neptune.


We did not need to collect any data for our project.



One day we might be able to live not only on Earth but also on Mars. With special technology and further scientific development humans might be able to live on Mars. The atmosphere on Mars contains oxygen for humans to breathe. The average temperature on Mars is really cold but humans could handle the temperature range with scientific advancements. Scientists are learning that there could have been water on Mars which could prove that there was once life on Mars. We can’t wait for the day we get to live on Mars.
