55576 Amycus ( /ˈæmɨkəs/), provisionally known as 2002 GB10, is a centaur discovered on April 8, 2002, by the NEAT at Palomar.
55576 Amycus was named for Amycus, a male centaur in Greek mythology.
It came to perihelion in February 2003.
Data from the Spitzer Space Telescope gave a diameter of 76.3 ± 12.5 km.
A low probability asteroid occultation of star UCAC2 17967364 with an apparent magnitude of +13.8 was possible on February 11, 2009.
Near 3:4 resonance of Uranus
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.
It has been observed 76 times over 19 years and has an orbit quality code of 2.
