Key Facts

Overview

11182 (1998 GM6) is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1998 GM6 as potentially hazardous because its orbit does not bring it close to Earth.

1998 GM6 orbits the sun every 1,630 days (4.46 years), coming as close as 2.70 AU and reaching as far as 2.72 AU from the sun. 1998 GM6 is about 12.2 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Cleveland, Ohio.

No Close Approaches

1998 GM6's orbit is 1.70 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

1998 GM6's orbit is determined by observations dating back to March 16, 1980. It was last officially observed on Feb. 10, 2023. The IAU Minor Planet Center records 3,446 observations used to determine its orbit.

Accessibility and Exploration

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