(1566) Icarus is a near-Earth asteroid (planetoid), from the group of the Apollo asteroids . These are heavenly bodies whose orbits can cross the earth's orbit.
This asteroid, about one kilometer in size, was discovered by Walter Baade on June 27, 1949 and has a relatively bright surface with an albedo of 0.4.
Icarus moves between 0.2 AU ( perihelion ) and 2 AU ( aphelion ) on a strongly elliptical orbit around the sun. This brings it closer to the sun than Mercury . For this reason it was named after Icarus , a tragic figure in Greek legend. With the help of self-made wings, it got too close to the sun and crashed.
