Overview

382395 (1990 SM) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1990 SM as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

1990 SM orbits the sun every 1,120 days (3.07 years), coming as close as 0.50 AU and reaching as far as 3.71 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 1990 SM is probably between 1.376 to 3.076 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.

Close Approaches

1990 SM's orbit is 0.03 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.

1990 SM has 8 close approaches predicted in the coming decades:
