Overview

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

Golevka orbits the sun every 1,430 days (3.92 years), coming as close as 0.96 AU and reaching as far as 4.01 AU from the sun. Golevka is about 0.5 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, comparable in size to the Golden Gate Bridge.

The rotation of Golevka has been observed. It completes a rotation on its axis every 6.03 hours.

Golevka's spectral type None (Tholen) / Q (SMASSII) indicates that it is likely to contain .

Close Approaches

Golevka's orbit is 0.02 AU from Earth's orbit at its closest point. This means that there is a wide berth between this asteroid and Earth at all times.

Golevka has 16 close approaches predicted in the coming decades:
