2011 GA
2011 GA is a small asteroid that is a Near-Earth object and an Apollo asteroid.
Orbit
The orbit of 2011 GA makes it a potentially hazardous asteroid (PHA) that is predicted to pass within 0.02 AU (3,000,000 km; 1,900,000 mi) of the Earth on Oct 14, 2023.[4] For comparison, the distance to the Moon is about 0.0026 AU (384,400 km). The asteroid passed within 0.06 AU (9,000,000 km; 5,600,000 mi) from Earth around October 15, 1977.
The Jupiter Tisserand invariant, used to distinguish different kinds of orbits, is 3.821.[2]
