Even today, it is frequently called the "Red Planet" because iron minerals in the Martian dirt oxidize, or rust, causing the surface to look red. Planet Mercury, Venus, Earth, and Mars What are the names of the 4 jovian planets in our solar system? Asteroids are also named for places and a variety of other things. Early in the history of the solar system, the gravity of newly formed Jupiter brought an end to the formation of planetary bodies in this region and caused the small bodies to collide with one another, fragmenting them into the asteroids we observe today. Uranus has a thick atmosphere made of methane, hydrogen, and helium. The orbits of asteroids can be changed by Jupiter's massive gravity and by occasional close encounters with Mars or other objects.
