1863 Antinous is an Apollo and Mars crosser asteroid, discovered in 1948 by Carl A. Wirtanen. It was named after Antinous of Greek mythology.
In the 20th century Antinous passed within 30 Gm of the Earth five times; it will do so only once in the 21st. The nearest distance increases each time, from 26 to 29 Gm.
