 | The surface temperatures of Mercury range from about 90 to 700 K (-183 *C to 427 *C). Also the surface of Mercury has been hit my meteors and comets so it has a surface similar to that of the moon. | |
|
| Well Mercury is also the densest planet in our solar system next to Earth.The smaller mass on Mercury makes the force of gravity only about one third of Earths. | |

|
| The atmsphere of Venus is about 872 *F. The surface also has thick opaque clouds of Sulfuric Acid, making us unable to see the surface of Venus. | |
|
| Venus also has an interior of lava and a hot dense core similar to Earth. it is called the sister planet to Earth because it has the same pressure and gravity as Earth. | |
|

|
|
|
| if Venus and the Earth were to evolve under similar conditions the differances that would exist today would be that Venus is obtained by a large cloud of Sulfiric acid. | |
|
| Today astronauts are unable to visit Mercury and Venus due to the extreme temperature differances from here on Earth. Human beings cannot take that kind of temperature exposure. | |
