Mercury Mercury is the closest planet to the sun. Mercury has no moons, but it still has nighttime. One day on mercury is 176 Earth days. Mercury has barely any atmosphere, so Mercury can easily be hit by an asteroid or meteor. It takes 88 earth days to orbit the sun. Earth’s moon’s crust is made out of what Mercury's crust is made out of, Silicates.

Venus Venus is the only planet the has a longer rotation than Mercury. Earth, Venus, and Mars all have about the same volume. Venus’ atmosphere has tons of sulfuric acid, so life cannot exist here. Venus reflects so much light that it can be seen at day on earth. It takes about 225 earth days to orbit the sun. One day on Venus is almost 243 Earth days!

Our home, Earth Earth is the only place in the Solar System where life exists. Over 600,000 species of plants and animals live here. Earth has one moon, it is also the only other place in space mankind has been. About 72% of Earth’s crust is water. The north pole is actually only ice. Earth

Mars, the Red Planet Mars and Earth both take about 24 hours to rotate. It takes Mars 436 days to revolve around the sun. Mars has two moons, so it is more likely to have a solar or lunar eclipse. Mars is red because of how much iron is in it’s crust. It is thought that mars had an atmosphere.

The Asteroid belt There are over 700,000 asteroids in the asteroid belt. One asteroid is so big, it actually has a gravitational pull! It also is considered a Dwarf Planet! The asteroid belt is in between Mars and Jupiter. Most of the asteroids are rock, but others are made out of ice.

Jupiter Jupiter is the closest gas planet to the sun. It is thought the giant red spot on Jupiter is a hurricane. Jupiter’s gravity is so strong, it ripped apart a comet! Jupiter is the largest planet in our Solar System. It has more mass than all the other planets combined!

Saturn Saturn is known for it’s rings, but all the other gas giants have rings too. Saturn rotates every 10 hours and 57 minutes. It takes 29 ½ earth years for Saturn to orbit the sun! Saturn’s rings are made out of ice. Saturn has more than 62 moons! One moon of Saturn has liquid water.

Uranus Uranus rotates on it’s side. It has the second most visible rings of the gas planets. Neptune and Uranus both have similar colors and density. Most people think that Uranus has a core, mantle, and an atmosphere. Uranus has at least 27 moons.

Neptune Neptune is the farthest planet from the sun. Neptune doesn’t have a crust. Neptune has at least 14 moons. Neptune’s largest moon, Triton, orbits in the opposite direction that Neptune rotates. Neptune has six pairs of rings. Neptune’s atmosphere blows winds at 900mi. Per hour.

Pluto Pluto is a dwarf planet, which means that it has a volume less than our moon. Pluto orbits the sun in an oval shape. Pluto goes through almost every planets orbit. Pluto is named after the god of the underworld in Roman mythology. Pluto’s surface is under -300 degrees Fahrenheit!
