Overview

466508 (2014 GY48) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2014 GY48 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2014 GY48 orbits the sun every 746 days (2.04 years), coming as close as 0.94 AU and reaching as far as 2.28 AU from the sun. Based on its brightness and the way it reflects light, 2014 GY48 is probably between 0.479 to 1.072 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.

The rotation of 2014 GY48 has been observed. It completes a rotation on its axis every 6.82 hours.

Close Approaches

2014 GY48'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.

2014 GY48 has 4 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
April 25, 2061 6,553,209 23.630
April 22, 2110 17,569,778 24.483
May 5, 2112 20,106,383 22.531
April 30, 2161 7,657,109 23.005
