Asteroids: The Building Blocks of the Solar System
Asteroids are rocky objects that orbit the Sun, mostly between Mars and Jupiter in the main asteroid belt. Some called Trojans, share the orbit of Jupiter and travel ahead or behind it. Asteroids are remnants of the early solar system when planets were forming from a d... | Cosmology & The Universe |
