It has a satellite orbiting it with a period of 11.9 hours, hence the appellation "Didymos", meaning "twin". The primary asteroid is about 800 m in diameter, the satellite is about 150 m in diameter in an orbit about 1.1 km from the primary. The rotation rate of Didymos is fast, 2.26 hours. Its density is 1.7±0.4 g/cm3. Didymos is the most easily reachable asteroid of its size from Earth, requiring a delta-v of only 5.1 km/s for a spacecraft to rendezvous compared to 6.0 km/s to reach the Moon. Its approach to Earth in November 2003 was especially close with a distance of 7.18 million km; it will not come that near until November 2123, with a distance of 5.9 million km. Didymos also passes very close to Mars: 4.69 million km in 2144.Didymos is the target of the European Space Agency's proposed AIDA probe.. }
