2004 JG6 (also written 2004 JG6) is one of the closest orbiting objects to the Sun.
It is the second known Apohele asteroid (the first being 163693 Atira), which means its entire orbit lies within that of the Earth.[2] Its orbital period is less than that of Venus, making it one of the closest known objects to the Sun, after Mercury. 2004 JG6 has an eccentric orbit that crosses the orbits of both Mercury and Venus.[2]
It was discovered by Brian A. Skiff of the LONEOS project.
