The following is a list of asteroids in our Solar System. For more specific details about any specific asteroid, please go to that asteroid's article by selecting its name from the table below. The first table below currently lists the eighteen largest known asteroids whose orbit is nearer to the Sun than that of Jupiter. The second table provides information about smaller asteroids of note.
In the tables below, "Number" refers to an asteroid's classification number--each asteroid, when discovered, is given a unique identifying number.
