Key Facts

Overview

7662 (1994 RM1) is a large asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified 1994 RM1 as potentially hazardous because its orbit does not bring it close to Earth.

1994 RM1 orbits the sun every 2,120 days (5.80 years), coming as close as 2.91 AU and reaching as far as 3.56 AU from the sun. 1994 RM1 is about 19.7 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Denver.

The rotation of 1994 RM1 has been observed. It completes a rotation on its axis every 80.31 hours.

No Close Approaches

1994 RM1's orbit is 1.95 AU from Earth's orbit at its closest point. This means that there is an extremely 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

1994 RM1's orbit is determined by observations dating back to Sept. 11, 1988. It was last officially observed on July 4, 2023. The IAU Minor Planet Center records 3,346 observations used to determine its orbit.

Accessibility and Exploration

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