Also includes the asteroid belt (the white donut-shaped cloud), the Hildas (the orange "triangle" just inside the orbit of Jupiter), the Jupiter trojans (green), and the near-Earth asteroids. The group that leads Jupiter are called the "Greeks" and the trailing group are called the "Trojans" (Murray and Dermott, Solar System Dynamics , pg. 107)

10 Hygiea is a major asteroid located in the main asteroid belt.With a mean diameter of between 425 and 440 km and a mass estimated to be 3% of the total mass of the belt, [11] it is the fourth-largest asteroid in the Solar System by both volume and mass, and is the largest of the C-type asteroids (dark asteroids with a carbonaceous surface) in classifications that use G type for 1 Ceres.
The radar images showed the asteroid is roughly spherical and is one of a pair, called a binary system. The space rock has a small moonlet orbiting it from a distance of 1.9 miles (3 kilometers).

An asteroid is a minor planet—an object that is neither a true planet nor an identified comet— that orbits within the inner Solar System.They are rocky, metallic, or icy bodies with no atmosphere, classified as C-type (carbonaceous), M-type (), or S-type (silicaceous).
