Going To Space By Jesus and Matt

What is a Solar System? It is a group of planets that orbit around the sun Began 5 billion years ago

Inner Planets Small, ball shaped Solid and rocky Have craters

The Sun Burning ball of gas Nearest star to earth It is 27,000,000 degrees F. It is a medium sized star. Over 100 Earths can go across the sun The Sun

Mercury Nearest to the sun One day is as long as a year Smallest planet No atmosphere creates lots of craters 750 degrees during the day -300 degrees at night Hot enough to melt metal

Venus Hottest planet because of thick carbon dioxide atmosphere It is 900 degrees F Surrounded by layer of clouds of sulfuric acid Volcanoes never run out of lava Very high winds

Earth Only planet with liquid water and oxygen to support life Protective blanket to air called atmosphere keeps harmful sunrays from hurting humans Earth

Mars Covered in red rocks made of iron oxide Polar ice caps-possibly underground water May have had water

Asteroid Belt Billions of fragments of rocks left over from the creation of the solar system Some pieces are dislodged and enter Earth’s atmosphere where they burn up are called meteorites or shooting star

Outer Planets They all have rings They are all gas planets Farthest from the sun Gas giants

Jupiter Biggest planet Diameter is 88,846 miles Has a spot called the Great Red Spot and is twice the size as Earth

Saturn Second largest planet Covered in thick clouds Rings are the brightest Rings made of ice , dust , and rocks

Uranus Third largest planet It is only one third the size of Jupiter Has 20 moons only five are large enough to be seen through a telescope

Neptune Neptune is the fourth largest planet in the solar system Has a spot, called The Great Dark Spot the same size as Jupiter’s spot It is very cold

Pluto Pluto is made of rock with a coating of ice A thin outer layer contains frozen methane, nitrogen, and carbon monoxide It is now a dwarf planet because of small size and goes through Neptune’s orbit and its lopsided
