Key Facts

Overview

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

Leejanel orbits the sun every 1,320 days (3.61 years), coming as close as 2.01 AU and reaching as far as 2.69 AU from the sun. Based on its brightness and the way it reflects light, Leejanel is probably between 2.424 to 5.421 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the island of Manhattan.

No Close Approaches

Leejanel's orbit is 1.00 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

Leejanel's orbit is determined by observations dating back to Nov. 27, 1994. It was last officially observed on Nov. 16, 2022. The IAU Minor Planet Center records 1,813 observations used to determine its orbit.

Accessibility and Exploration

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