Mercury is the smallest planet in the solar system and it sits closer to the sun than any of the other planets. Of the eight planets four are terrestrial including Mercury. Little is known about this planet in relation to the other terrestrial planets in space.
Mercury has had little exploration done and much more is still to be found out. It does however have more surface craters than any other planet as seen from telescopes. So much so that it resembles the moon's surface. This planet has been explored slightly at least on two occasions. In the mid 70's the Mariner 10 shuttle flew past the planet and The Messenger which was sent out into space in 2004 still after ten years continues to orbit near Mercury.

Venus is the second planet from the sun and aside from the moon it's the brightest object in the sky at night that can be seen. It's one of the four terrestrial planets and it's the densest terrestrial planet with over 96% carbon dioxide. It's the hottest of all the solar system's planets reaching temperatures as high as 860 F.
Venus has had many pictures taken of it and learning this planet has only just begun. Venus has no natural satellite of any kind. Venus is the closest planet to earth in terms of miles and the planet's size.
Earth is the third planet from the sun and it's also the densest planet in our solar system. It's a terrestrial planet and more than 70% of earth is covered by water.
Earth has four seasons which are winter, spring, summer and fall. The first human to orbit around planet earth was Yuri Gagarin and he did so in 1961.

Jupiter is the largest planet in the solar system and it's one of four planets called Gas Giants. Jupiter is the fifth planet from the sun and it is composed primarily of Hydrogen and less than ten % Helium.
With the size of Jupiter and it's distance from Earth we are still far away from learning and discovering all there is to know about this humongous planet. It's composed mostly of Hydrogen with small amount of Helium and it is known for having what is called The giant Red Spot. This spot resulted from super strong turbulence, winds and storms.

The Earth and Neptune
Neptune is the farthest planet from the sun and the eighth planet in our planetary solar system. It's a Gas Giant and the planets insides are mainly composed of rocks and ice. Winds reach near supersonic speeds of up to 1,200 MPH.
Neptune was first discovered in 1612 by Galileo but he did not realize what he found and in 1846 it was made an official discovered planet. In 1989, The Voyager 2 made a relatively close fly by and took snap shots.
Uranus and the Earth
Uranus is the seventh planet from the sun and it's a Gas Giant. Plant Uranus is the third biggest planet in our solar system and it's known to have the coldest atmosphere of all the eight planets. Winds on Uranus can reach speeds of almost 600 MPH.
So far we know enough about this planet to stay far way or get frozen and blown away by the winds. Neptune has Three main planetary rings are thought to consist of ice particles or even possible some Carbon type items. Uranus was discovered in 1781 and it's the first planet to be discovered with an advanced telescope.
