55576 Amycus /ˈæmɪkəs/ is a centaur discovered on 8 April 2002 by the NEAT at Palomar.[1]
The minor planet was named for Amycus, a male centaur in Greek mythology.
It came to perihelion in February 2003.[1] Data from the Spitzer Space Telescope gave a diameter of 76.3±12.5 km.[4][5]
A low probability asteroid occultation of star UCAC2 17967364 with an apparent magnitude of +13.8 was possible on 11 February 2009.[8] Another such event involving a star with an apparent magnitude of +12.9 occurred on 10 April 2014 at about 10:46 Universal Time, visible for observers in the southwest US and western Mexico.[9]
