Tour of Our Solar System: Vuelta a Nuestro Sistema Solar
Mercury : The First Planet
Even made the picture small to show how it is the second smallest;)
|
Mercury is the second smallest planet in our solar system. It is also the closest to the Sun. The surface of Mercury is a lot like our very own moon. It is covered in craters, some of which have two rings. The magnetic field around Mercury suggest that it has a much larger iron core then most would suspect.

Venus: The Second
Venus is second in line in our solar system. It is relatively like our home planet Earth. It's mass and size are nearly identical! However, Venus differs from Earth in the fact that it has a very dense atmosphere. It is 92 times the Earth's pressure and is made up of mostly carbon dioxide. The clouds in the atmosphere contain sulfuric acid which gives them a slightly yellow look. There is a greenhouse effect on Venus' surface.
Earth: The Third
Our home planet is the third planet from the Sun. The surface temperature on Earth is ideal for water to exist as a solid, liquid, and gas. Our atmosphere cause the majority of meteors to burn up before they reach our surface. Our atmosphere also protect us from the sun's harmful rays. Life thrives all over our planet even in intense climates.
Mars: The Fourth
Mars is the Fourth planet from the Sun. It is known as the red planet because of the iron oxide found in it's surface rocks. Mars actually is on a 25% tilt on it's axis which is a lot like Earth. For this reason, it goes through seasons just like Earth. The color of Mars surface changes with the seasons.
Jupiter : The Fifth
Jupiter is the Fifth planet from the sun. It is the largest planet. Jupiter is composed mostly of hydrogen and helium. They also believe that below Jupiter's liquid layer there may be a rocky core much larger than Earth's. Swirling storms of high pressure gas has been observed on Jupiter. The Great Red Spot is the most spectacular of the storms.
Saturn: The Sixth
Saturn is the sixth planet from the Sun. It has the largest and most complex ring system. Saturn could have at the least 34 moons! Even though Saturn is one of the largest planets, it has the lowest density because it's gravitational pull is weak. It is speculated that Saturn may have a small rocky core. Saturn's rings are made up of lots of rock and ice particles.
Uranus: The Seventh
Uranus is the seventh planet from the Sun. It wasn't discovered until 1781 and has 27 moons. Uranus has several thin ringlets around it. It's atmosphere contains hydrogen, helium, and 2% methane. The methane is what gives Uranus it's blue color. You can not see storms on Uranus because of the cold upper atmosphere.
Neptune: The Eighth
Neptune is the eighth planet from the Sun. It is similar in size to Uranus and was discovered in 1846 by Uranus's orbit showed another object must be pulling on it. It has rings surrounding it that are thin in some places and thick in others. With 3% methane it appears bluer than Uranus and it's dynamic atmosphere shows that it has a greater internal heat than Uranus.
Pluto: The Ninth
Pluto is the ninth planet from the Sun and also the smallest. It is has a thin atmosphere and is the ONLY outer planet with a solid ice-rock surface. Pluto has only one moon named Charon though it is very large compared to Pluto and orbits close to it.
