1566 Icarus is an Apollo asteroid (a sub-class of near-Earth asteroid). At its closest approach to the Sun (perihelion) it is closer to the Sun than Mercury. In its orbit it crosses the orbits of Mercury, Venus and Mars. It is named after Icarus of Greek mythology, who flew too close to the Sun. The asteroid was found in 1949 by Walter Baade.
