Overview

108519 (2001 LF) is a mid-sized asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2001 LF as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

2001 LF orbits the sun every 742 days (2.03 years), coming as close as 1.17 AU and reaching as far as 2.04 AU from the sun. 2001 LF is about 1.4 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. Pentagon.

The rotation of 2001 LF has been observed. It completes a rotation on its axis every 4.50 hours.

Close Approaches

2001 LF's orbit is 0.16 AU from Earth's orbit at its closest point. This means that there is a wide berth between this asteroid and Earth at all times.

2001 LF has 3 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
June 13, 2072 25,123,809 8.993
June 16, 2137 27,591,992 8.735
June 15, 2139 27,559,287 9.205

Images and Observations

2001 LF's orbit is determined by observations dating back to Sept. 8, 1989. It was last officially observed on Jan. 20, 2023. The IAU Minor Planet Center records 931 observations used to determine its orbit.
