Overview

2003 SU84 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2003 SU84 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.

2003 SU84 orbits the sun every 670 days (1.83 years), coming as close as 0.92 AU and reaching as far as 2.08 AU from the sun. Based on its brightness and the way it reflects light, 2003 SU84 is probably between 0.101 to 0.226 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2003 SU84's orbit is 0.13 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.

2003 SU84 has 8 close approaches predicted in the coming decades:
