Kuiper belt object 136108 Haumea is one of the most fascinating bodies in our solar system. Approximately 2000x1600x1000 km in size, it is one of the largest Kuiper belt objects (KBOs) and an unusually elongated one for its size.

Millions of asteroids are winging around the solar system, but which ones do we have to fear? Browse these images of our ominous neighbors to find out.
