Key Facts

Overview

2010 LB136 is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2010 LB136 as potentially hazardous because its orbit does not bring it close to Earth.

2010 LB136 orbits the sun every 91,400 days (250.24 years), coming as close as 29.00 AU and reaching as far as 50.44 AU from the sun. Based on its brightness and the way it reflects light, 2010 LB136 is probably between 139.494 to 311.918 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Maryland.

No Close Approaches

2010 LB136's orbit is 28.00 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

2010 LB136's orbit is determined by observations dating back to June 4, 2010. It was last officially observed on Aug. 15, 2020. The IAU Minor Planet Center records 48 observations used to determine its orbit.

Accessibility and Exploration

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