1. Rathdown Star Surfers P6 G project 2010

2. Mars • Mars is a rocky planet and it has a similar make up to earth. • It is small and red in colour. • Mars is more like earth than any other planet. • It is too cold and the atmosphere is too thin for life to exist. • The diameter of mars is 6,787 km. • The average distance from the sun on mars is 228 million km.

3. The Moon • The moon takes 27 days to go all the way around earth and return to its starting point. • The Moon is 4.5 billion years old. • The moon has a diameter of 2000 miles. • The moon has no atmosphere . • The moon rises and sets at approximately the same time as the sun.

4. The sun • The Sun is the closest star to earth but it is not the biggest star. • The Sun is an ordinary star made up of boiling hot gases. • The sun is personified in many mythologies: the Greeks called it Helios and the Romans called it Sol. • The sun is made out of 92% hydrogen, 7% helium and the rest is lower gases.

5. Pluto • Pluto is no longer a planet anymore, it is a dwarf planet. • Pluto has an atmosphere. • Pluto was first discovered in 1985. • Pluto has three moons one of these is Charon which is half of Pluto's size. • Pluto is named after a god, not a dog! • If Pluto was closer to the sun, Pluto would be a comet.

6. Mercury • It is the closest planet to the sun that is why it is boiling hot. • The Planet mercury is not very big, it has a diameter of about 4880km which is only about a third of the size of the earth. • Mercury is one of the few planets which has neither moons nor satellites captive within it’s gravity well.

7. Venus • Venus is the hottest planet I our solar system. • Venus is also known as the morning star. • Venus takes 225 days to orbit the sun. • Venus is known as the earth’s twin. • Venus’s atmosphere is 96.5% carbon dioxide and the rest is green house gases.

8. Earth • From a distance Earth would be the brightest of the nine planets. • The Earth is 4.6 billion years old. • The Earth is the third planet from the sun. • The Earth travels through space at 66,700 miles per hour.

9. Uranus • Uranus is the seventh planet from the Sun. • Uranus is very, very cold. • Uranus spins on its side. • A day on Uranus is seventeen hours. • Uranus is made up of gas. • Uranus has 27 moons. • Uranus was the first planet discovered by telescope . • It has faint rings.

10. Jupiter Jupiter is the fifth planet from the Sun. Jupiter takes about 12 years to orbit the sun. Jupiter is the largest planet in the solar system. Jupiter is a gas planet held together by a massive gravity field.

11. Saturn • Saturn spins so quickly on its axis that the planet flattens itself. • Saturn is the least dense planet in the solar system. • Saturn has only been visited 4 times by spacecraft. • The fascinating ring system observed by Galileo in 1610 is only beginning to be understood. • Saturn has 60 moons.

12. Neptune • Neptune is the 8th planet from the sun in our solar system. • Neptune is named after the Roman God of the sea. • Neptune has 13 moons. • Neptune was discovered on September 23rd 1846. • Neptune was the first planet discovered by mathematical prediction.
