It is an B-type asteroid, which is composed of silicate rocks and metals. The asteroid is roughly estimated to have a diameter of 317 miles (511 kilometers), making it the third largest object in the asteroid belt. 2 Pallas has an eccentric orbit, which means it follows an elliptical path around the sun. It has an orbital period of 4.6 years and a perihelion of 2.1 AU. 2 Pallas has a low albedo, which means the surface is dark and absorbs more sunlight than it reflects.
