Our solar system The Sun • • • • The Sun is the centre of our solar system Also the Sun is the largest star in the universe. The Sun is made out of nitrogen, helium and hydrogen. The Sun gives life to the Earth and the Earth would have no life from the energy of the sun. • The sun is only millions and millions of stars in the galaxy Mercury • Mercury is the first planet in our solar system • Mercury is covered with many craters • Mercury has a very low surface gravity • Mercury has a very low surface gravity • Mercury is very hot • Mercury is 58,000,000 km away from the sun • It takes 0.2 years to orbit the sun • The mass of this planet is 0.8 • It is a +112 degrees Celsius Venus • Mercury has a very low surface gravity • Venus features no liquid water. • Its size is slightly smaller than Earth • It also features gravity similar to that of Earth • Venus is the second planet • Venus takes 0.6 years to orbit the sun • The relative mass is 0.6 • The distance from the sun is 108,000,000km • It is +470 degrees Celsius The Moon • The moon comes out at night • Also the Moon circles the Earth • Neil Armstrong was the first person to land on the moon • The Moon has also got many craters like Mercury • The moon orbits the Earth every 27.5 days . Earth • Earth has a very big life source • Was created by a big bang • Also the Earth has a lot of oxygen • The Earth is the 4th planet • It takes 365 days to orbit the sun. • The relative mass is 1 • It also takes a year to orbit the sun • The average distance is 150,000,000 km away from the sun • It is +15 degrees Celsius The ISS The international space station is 400 KM away from Earth. It orbits at a 51.65 degree angle. It is 255 miles above Earth Mars • Mars is the 5th planet in our solar system • Famous scientists is planning to visit mars • Mars has a tiny bit of water on it • The relative mass is 0.1 • It takes 1.9 year to orbit the sun • The distance is 228,000,000 km away from the sun • The temperature is -30 degrees Celsius • Jupiter • Jupiter is a very big planet • It is the 6th planet in our solar system • the Sun, is about 2 and a half miles away from Jupiter. • Jupiter is a gas giant • The relative mass is 320 • It takes 12 years to orbit the sun • It is 778,000,000 km away from the sun • It is a freezing -150 degrees Celsius Saturn • • • • • • • Saturn is the 7th planet Saturn has a great big ring around it Saturn is nine times as big as Earth Saturn is also a gas planet as well as Jupiter. The relative mass is 95 It takes 30 years to orbit the sun The huge distance is 1427,000,000km away from the sun • Its -180 degrees Celsius Uranus • • • • Uranus is the 8th planet Uranus is very cold. Uranus is 2nd from last of Neptune Uranus can not bee seen from Earth Neptune • Neptune is the last planet • Neptune is the coldest planet • It can not be seen from Earth as well as Uranus • Neptune is one of the four gas giants
