Overview

141527 (2002 FG7) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2002 FG7 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2002 FG7 orbits the sun every 680 days (1.86 years), coming as close as 0.56 AU and reaching as far as 2.46 AU from the sun. Based on its brightness and the way it reflects light, 2002 FG7 is probably between 0.433 to 0.968 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 2002 FG7 has been observed. It completes a rotation on its axis every 6.31 hours.

Close Approaches

2002 FG7's orbit is 0.04 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.

2002 FG7 has 12 close approaches predicted in the coming decades:
