Overview
415745 (2000 GV147) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2000 GV147 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2000 GV147 orbits the sun every 843 days (2.31 years), coming as close as 0.95 AU and reaching as far as 2.54 AU from the sun. Based on its brightness and the way it reflects light, 2000 GV147 is probably between 0.349 to 0.780 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to the U.S. Capitol building.
Close Approaches
2000 GV147's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
2000 GV147 has 9 close approaches predicted in the coming decades:
