Asteroids

Asteroids are Minor Planets especially those of the Inner Solar System

The large majority of known asteroids orbit in the asteroid belt between the orbits of Mars and Jupiter, or are co-orbital with Jupiter

However, other orbital families exist with significant populations, including the near Earth asteriods Individual asteroids are classified by their characteristic spectra, with the majority falling into three main groups - C-type;S-type and M-type

Only one asteroid,4 Vesta, which has a relatively reflective surface, is normally visible to the naked eye, and this only in very dark skies when it is favorably positioned

Rarely, small asteroids passing close to Earth may be visible to the naked eye for a short time
