Planets Out of Our World

Earth is where we live but we don’t know if there might be life somewhere else! We know nearly everything about our solar system so it’s time to find about another world.

There’s a rocky core planet in a different solar system that’s as big as Jupiter. We know about from using a spacecraft. Uranus was the last to be seen with the telescope.

Neptune was seen with the naked eye along with Pluto and the other dwarf planets. Our sun [Sol] is known to be the smallest star but it’s not, Sirius is!

Sirius is big but Sirius B isn’t. It’s only as big as Saturn! It’s so small you can only see Sirius. Betelgeuse is about to explode but it’s so far away it won’t reach us. It’s a red giant. Sirius and Sirius B are blue giants. Our sun Sol is a medium yellow star. So that means the stars are bigger than you think. More than 100 billion stars are in our galaxy. Galaxies make light in the black, dark areas.

Venus

Venus is the only planet with a girl’s name.  Venus is named after the Roman goddess of love and beauty.  

Venus is called the  morning star and evening star because Venus comes up before the sun and goes down before the sun in the evening.

Venus is a rocky dwarf just like Earth and is our nearest neighbouring planet, but we have never really seen it because it is always surrounded by thick clouds.

Venus’s diameter is 12048 km and it is 107 million km from the sun. Venus takes 225 earth days to orbit around  the sun. A day on Venus is 116 earth days long.

Starlab

I looked up and saw the stars. There was a red arrow in the stars. Gloria was talking as she was controlling the red arrow. She used the arrow to point at the stars and tell us about them.

There are coloured stars. They are red, yellow, white and blue. Now I will tell you the shapes of the stars.  One is Scorpio and another one is the Southern Cross. Stars twinkle and planets don’t twinkle, that’s how you tell them apart.

She gave us two meteorites. One was iron and one was rocky.  The rocky one had a cut so you can see inside the meteor. Then she said stand up and go out (politely). Then we put our shoes on and went to boring old class.

Saturn

Saturn is a gas giant planet. Saturn is a planet in the Solar System. The closest planets to Saturn are Jupiter and Uranus.

Saturn has rings made out of tiny bits of snow, small pieces of ice stones, and rocks. They form a ring because they orbit Saturn like Saturn orbits the sun.

Saturn is 1 433 000 000 Km from the Sun and is 120,636 km in diameter. A day on Saturn lasts for 10 hours and 39 minutes and a complete orbit around the Sun (1 Saturn year) takes 29.5 Earth years.

Uranus

Uranus  is named after a greek god.  Uranus  was the son and mate of Gaia and the father of Saturn.

It was discovered by William Herschel on March 13th,7 1781. Uranus is covered in blue clouds. The clouds are made of methane and are difficult to see as they are low in the atmosphere.

Did you know that Uranus is the seventh planet  from the sun. It is the 3rd biggest planet  and it is an Ice Giant.  It has 12 rings and 27 moons.  

It is 51000 km in diameter and 2 877 000 000 km  from the sun.  Its day is 17 hours and 14 minutes long  and a year on Uranus lasts for 84 Earth years.

Mercury

Mercury is named for the Roman messenger to the gods. Mercury is the smallest planet in the Solar System and the closest to the sun.

Mercury has a dark grey, rocky surface which is covered with a thick layer of dust. Mercury is covered in craters like the moon.

Its temperature is -173 to 427C.  From one side to the other is 4880 Km and its mass is 330,104,000,000,000 billion KGs.

Mercury moves in an orbit around the Sun which lies within Earth’s sky in the morning or the evening, but not in the middle of the night. One year on Mercury is 88 days.

Mercury has no moons at all.  Mercury has a molten core.  Even though Mercury is the closest to the sun it is only the second hottest planet.
