8  Has a carbon dioxide atmosphere 90 times thicker than that of Earth causing an efficient greenhouse effect by which the Venusian atmosphere is heated. The resulting surface temperature is the hottest of any planet about 4770 C (about 8900 F). Droplets of sulfuric acid give the clouds of Venus a yellow color . Venus has retrograde or opposite rotation from that of most other planets. Rotation is extremely slow Earth-days.

 ½s the only planet known to have abundant liquid water and life. However, in 2004 astronomers with the National Aeronautics and Space Administration¶s Mars Exploration Rover mission confirmed once had liquid water on its surface. Scientist had previously concluded thatliquid water once existed on Mars due to the numerous surface features on the planet that assemble water erosion found on Earth.

Å


 

½s the fourth planet from the sun. it is known as the Red planet because of the reddish color of the dust that covers it, although sometimes dark areas of rock show up when storms blow away the dust. Mars¶s carbon dioxide atmosphere is now so thin that the planet is dry and cold, with color caps of frozen water and solid carbon dioxide, or dry ice. However, small jets of sub crustal water may still erupt on the surface in some places. Mars has many volcanoes, all of which are now believe to be extinct..

M 

M 
is the largest of the planets. ½t is big enough to contain all the other planets put together . Known as a ³gas giant´, because of its thick gassy outer layer. ½ts hydrogen and helium atmosphere contains colored clouds, and its immense magnetosphere, rings, and satellites make it a planetary system unto its self. One of Jupiter¶s largest moons, ½ has volcanoes that produce the hottest surface temperatures in the solar system. At least four of Jupiter¶s moons have atmospheres, and at least three may contain liquid or partially frozen water Jupiter¶s moon. 4
 may have a global ocean of liquid water beneath its icy crust.
  the largest of all solar system satellites, half rock, half ice.

 ½s 95 times more massive than Earth. Although it is the second largest planet, Saturn has the lowest density. Saturn would float on water. ½t has more than 20 satellites. The largest of it is ½
 which has a dense atmosphere.

d
 ñas discovered in 1781 by German astronomer ñilliam Hershel. ½t was the first planet to be discovered using a telescope. ½t is a gaseous planet with at least 10 dark rings, 10 are ± shaped pieces of rings, and 15 satellites. ½t has a retrograde rotation. ½t is thought to be made of hydrogen and methane gases.

 ½s also gaseous planet similar in size and composition to Uranus. ½t appears to be surrounded at least 3 partial ring arcs less than 20 kilometers wide. Neptune has 2 satellites one of which, ½
is larger than Pluto.
