Overview

54071 (2000 GQ146) is a mid-sized asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2000 GQ146 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

2000 GQ146 orbits the sun every 560 days (1.53 years), coming as close as 1.07 AU and reaching as far as 1.59 AU from the sun. Based on its brightness and the way it reflects light, 2000 GQ146 is probably between 0.868 to 1.941 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the Golden Gate Bridge.

The rotation of 2000 GQ146 has been observed. It completes a rotation on its axis every 51.00 hours.

Close Approaches

2000 GQ146's orbit is 0.12 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.

2000 GQ146 has 7 close approaches predicted in the coming decades:
