Key Facts

Overview

8481 (1988 LH) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1988 LH as potentially hazardous because its orbit does not bring it close to Earth.

1988 LH orbits the sun every 1,920 days (5.26 years), coming as close as 2.38 AU and reaching as far as 3.67 AU from the sun. 1988 LH is about 8.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

The rotation of 1988 LH has been observed. It completes a rotation on its axis every 15.52 hours.

No Close Approaches

1988 LH's orbit is 1.38 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

1988 LH's orbit is determined by observations dating back to May 8, 1956. It was last officially observed on March 18, 2023. The IAU Minor Planet Center records 3,500 observations used to determine its orbit.

Accessibility and Exploration

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