Overview

483423 (2000 DO1) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2000 DO1 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2000 DO1 orbits the sun every 624 days (1.71 years), coming as close as 0.46 AU and reaching as far as 2.40 AU from the sun. Based on its brightness and the way it reflects light, 2000 DO1 is probably between 0.208 to 0.466 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

2000 DO1's spectral type None (Tholen) / V (SMASSII) indicates that it is likely to contain and .

Close Approaches

2000 DO1's orbit is 0.01 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.

2000 DO1 has 13 close approaches predicted in the coming decades:
