Overview

2013 JX28 is a very small asteroid with an orbit that is entirely confined within Earth's orbit. NASA JPL has classified 2013 JX28 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 JX28 orbits the sun every 170 days (0.47 years), coming as close as 0.26 AU and reaching as far as 0.94 AU from the sun. Based on its brightness and the way it reflects light, 2013 JX28 is probably between 0.254 to 0.568 kilometers in diameter, making it small in absolute terms, but larger than 90% of asteroids, very roughly comparable in size to a football field.

Close Approaches

2013 JX28's orbit is 0.07 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.

2013 JX28 has 35 close approaches predicted in the coming decades:
