Overview

2019 XD is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2019 XD 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.

2019 XD orbits the sun every 337 days (0.92 years), coming as close as 0.79 AU and reaching as far as 1.10 AU from the sun. Based on its brightness and the way it reflects light, 2019 XD is probably between 0.009 to 0.020 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2019 XD's orbit is 0.02 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.

2019 XD has 10 close approaches predicted in the coming decades:
