If you were to live on Neptune, you would not live very long because it takes 165 earth years to revolve around the sun and you would probably not live to be 1. However it takes only 17 earth hours to rotate. Neptune is also a gas giant and 8th from the sun. Neptune is 49,528 KM. Methane on it's atmosphere gives it the blue color.Neptune is 4 1/2 billion km from the sun.
Mars
That is a great fact!
If you were to live on Venus it would have been almost Impossible to keep time because 1 day is longer than 1 year! I know it sounds crazy but 1 year takes 225 earth days and 1 day on Venus is 243 days on earth. Venus has thick gases around it that traps heat from the sun and that is what makes it very hot.
Stars
The sun is the only star in our universe!
HELP US PLEASE
Uranus is a gas giant. To get to Uranus you have to travel past the inner planets. Then you have to go threw a astro belt. Finally you pass Jupiter and Saturn to see Uranus. It was also the first planet seen in a telescope. Uranus also is the only planet that rotates on it's side.
Pluto
We are freezing our butts off here on Pluto!!!
Mars is the 4th planet from the sun. The surface of Mars has many craters, holes, mountains and volcanoes. Mars has the largest volcano in the solar system. Mars gets a lot of heat because it is so close to the sun.
The sun is acctually a star. The sun is about 150 million km away. Stars are different sizes. Some are white dwarfs witch are the size of earth. Others are red or yellow dwarfs. One other one is a blue giant. When a star explodes the gases can form back together to make new star.
Pluto is a dwarf planet that used to be called a planet. It is very far from the sun. One man made a goal to go to pluto but died before he could. Then a robotic spaceship took this man's ashes to pluto. Pluto has 5 moons.
