Overview

525484 (2005 GL) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2005 GL as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2005 GL orbits the sun every 397 days (1.09 years), coming as close as 0.73 AU and reaching as far as 1.38 AU from the sun. Based on its brightness and the way it reflects light, 2005 GL is probably between 0.146 to 0.327 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2005 GL's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2005 GL has 24 close approaches predicted in the coming decades:
