Overview
2015 BZ310 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2015 BZ310 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2015 BZ310 orbits the sun every 1,060 days (2.90 years), coming as close as 0.90 AU and reaching as far as 3.16 AU from the sun. Based on its brightness and the way it reflects light, 2015 BZ310 is probably between 0.145 to 0.324 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.
The rotation of 2015 BZ310 has been observed. It completes a rotation on its axis every 5.90 hours.
Close Approaches
2015 BZ310'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.
2015 BZ310 has 9 close approaches predicted in the coming decades:
