1865 Cerberus is an Apollo and a Mars crosser asteroid, discovered in 1971 by Luboš Kohoutek [1] and named in 1974[4]
Cerberus is composed of 65% plagioclase and 35% pyroxene,[5] and passes within 30 Gm (Gigameters) of the Earth 7 times from the year 1900 to the year 2100, each time at a distance of 24.4 Gm to 25.7 Gm. It is named after the guard dog of the Underworld. It also makes close approaches to Mars and Venus.
