Overview

509352 (2007 AG) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2007 AG as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2007 AG orbits the sun every 223 days (0.61 years), coming as close as 0.45 AU and reaching as far as 0.99 AU from the sun. Based on its brightness and the way it reflects light, 2007 AG is probably between 0.247 to 0.552 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to a football field.

Close Approaches

2007 AG's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2007 AG has 32 close approaches predicted in the coming decades:
