8160 (1990 MG)

Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to the San Francisco Bay
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

8160 (1990 MG) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1990 MG as potentially hazardous because its orbit does not bring it close to Earth.

1990 MG orbits the sun every 1,180 days (3.23 years), coming as close as 1.78 AU and reaching as far as 2.60 AU from the sun. Based on its brightness and the way it reflects light, 1990 MG is probably between 3.703 to 8.280 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.

The rotation of 1990 MG has been observed. It completes a rotation on its axis every 3.72 hours.

No Close Approaches

1990 MG's orbit is 0.77 AU from Earth's orbit at its closest point. This means that there is a very wide berth between this asteroid and Earth at all times.

Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.

Images and Observations

1990 MG's orbit is determined by observations dating back to April 28, 1957. It was last officially observed on Oct. 26, 2022. The IAU Minor Planet Center records 2,926 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
