OverviewFormation and evolutionGeneral characteristicsSunInner Solar SystemOuter Solar SystemTrans-Neptunian regionMiscellaneous populations

The Solar System is the gravitationally bound system of the Sun and the objects that orbit it. It formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc. The Sun is a typical star that maintains a balanced equilibrium by the fusion of hydrogen into helium at its core, releasing this energy from its outer photosphere. Astronomers

Inner Planets | Earth Science

From left to right, they are Mercury, Venus, Earth, and Mars. Unlike the outer planets, which have many of satellites, Mercury and Venus do not have moons, Earth has one, and Mars has two. Of course, the inner planets have shorter orbits around the Sun, and they all spin more slowly. Geologically, the inner planets are all made of cooled

Gravitational Pull of the Planets

Mars has a very low gravitational pull of only 3.71 m/s2. If you weigh 100 lbs on Earth you would only come in around 38 lbs on the red planet. 8. At 3.7 m/s2, Mercury''s gravitational pull almost exactly the same as that of Mars. Someone weighing

Terrestrial Planet Facts (The Inner Planets)

The four innermost planets of our solar system (Mercury, Venus, Earth and Mars) are called the "terrestrial" planets.

ATMOSPHERES OF THE TERRESTRIAL PLANETS

The Terrestrial planets (Mercury, Venus, Earth, Moon, Mars) are similar to each other in mass, diameter, and distance from the Sun. Because of this, it is expected that their atmospheres should share many similar qualities. The atmospheric masses are in the rough ratio of 100:1:0.01 for Venus:Earth:Mars (based on their atmospheric pressures).

Comparison of Earth, Venus, Mars

•A spectacular difference between the early history of Earth and Venus is that the Earth was struck in a glancing impact by a Mars-size bolide after 90% formation. The rubble thrown into space formed the moon; this impact-origin model explains the very large angular moment of the earth-moon system (and other things). Note while the Earth spins
