Overview

436030 (2009 JO2) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2009 JO2 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.

2009 JO2 orbits the sun every 306 days (0.84 years), coming as close as 0.46 AU and reaching as far as 1.31 AU from the sun. 2009 JO2 is about 0.3 kilometers in diameter, making it a small to average asteroid, comparable in size to a football field.

Close Approaches

2009 JO2's orbit is 0.06 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.

2009 JO2 has 16 close approaches predicted in the coming decades:
