Overview

2013 JR22 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2013 JR22 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

2013 JR22 orbits the sun every 1,000 days (2.74 years), coming as close as 0.54 AU and reaching as far as 3.38 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2013 JR22 is probably between 0.178 to 0.398 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2013 JR22's orbit is 0.12 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.

2013 JR22 has 12 close approaches predicted in the coming decades:
