Overview

2012 VE46 is a very small asteroid with an orbit that is entirely confined within Earth's orbit. NASA JPL has classified 2012 VE46 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2012 VE46 orbits the sun every 220 days (0.60 years), coming as close as 0.46 AU and reaching as far as 0.97 AU from the sun. Based on its brightness and the way it reflects light, 2012 VE46 is probably between 0.242 to 0.542 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2012 VE46's orbit is 0.03 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.

2012 VE46 has 28 close approaches predicted in the coming decades:
