Overview

152828 (1999 VT25) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1999 VT25 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

1999 VT25 orbits the sun every 458 days (1.25 years), coming as close as 0.55 AU and reaching as far as 1.77 AU from the sun. Based on its brightness and the way it reflects light, 1999 VT25 is probably between 0.147 to 0.330 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

1999 VT25's orbit is 0.05 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.

1999 VT25 has 11 close approaches predicted in the coming decades:
