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]
Amycus (2002 GB10) lies within 0.009 AU of the 3:4 resonance of Uranus and is estimated to have a long orbital half-life of about 11.1 Myr. [10] [11]
