4055 Magellan (1985 DO2) is an Amor asteroid discovered on February 24, 1985, by E. Helin at Palomar. Based upon the spectrum, it is compositionally similar to 4 Vesta. It has a high albedo of 0.31.[1]
Photometric observations of this asteroid in 2010 show a rotation period of 7.488 ± 0.001 hours, with a brightness variation of 0.8 magnitude. The large variation suggests an elongated shape.[1]
