Key Facts

Overview

9773 (1993 MG1) is a mid-sized asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified 1993 MG1 as potentially hazardous because its orbit does not bring it close to Earth.

1993 MG1 orbits the sun every 1,600 days (4.38 years), coming as close as 1.64 AU and reaching as far as 3.72 AU from the sun. 1993 MG1 is about 4.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.

The rotation of 1993 MG1 has been observed. It completes a rotation on its axis every 2.75 hours.

No Close Approaches

1993 MG1's orbit is 0.63 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

1993 MG1's orbit is determined by observations dating back to Sept. 30, 1989. It was last officially observed on May 23, 2023. The IAU Minor Planet Center records 2,429 observations used to determine its orbit.

Accessibility and Exploration

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