Overview

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

Anagolay orbits the sun every 908 days (2.49 years), coming as close as 1.02 AU and reaching as far as 2.65 AU from the sun. Anagolay is about 0.5 kilometers in diameter, making it a small to average asteroid, comparable in size to the Golden Gate Bridge.

The rotation of Anagolay has been observed. It completes a rotation on its axis every 9.01 days.

Close Approaches

Anagolay's orbit is 0.04 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.

Anagolay has 7 close approaches predicted in the coming decades:
