Key Facts

Overview

105140 (2000 NL10) is a mid-sized asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2000 NL10 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.

2000 NL10 orbits the sun every 319 days (0.87 years), coming as close as 0.17 AU and reaching as far as 1.66 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2000 NL10 is probably between 1.839 to 4.112 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.

The rotation of 2000 NL10 has been observed. It completes a rotation on its axis every 6.93 days.

No Close Approaches

2000 NL10's orbit is 0.36 AU from Earth's orbit at its closest point. This means that there is an 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

2000 NL10's orbit is determined by observations dating back to Sept. 17, 1952. It was last officially observed on Oct. 27, 2019. The IAU Minor Planet Center records 1,954 observations used to determine its orbit.

Accessibility and Exploration

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