Overview

144900 (2004 VG64) is a small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2004 VG64 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2004 VG64 orbits the sun every 348 days (0.95 years), coming as close as 0.33 AU and reaching as far as 1.60 AU from the sun. Based on its brightness and the way it reflects light, 2004 VG64 is probably between 0.584 to 1.306 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.

Close Approaches

2004 VG64's orbit is 0.03 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.

2004 VG64 has 13 close approaches predicted in the coming decades:
