Key Facts

Overview

523782 (2015 BD518) is a large asteroid with an orbit between Jupiter and Neptune. NASA JPL has not classified 2015 BD518 as potentially hazardous because its orbit does not bring it close to Earth.

2015 BD518 orbits the sun every 40,700 days (111.43 years), coming as close as 16.26 AU and reaching as far as 30.08 AU from the sun. Based on its brightness and the way it reflects light, 2015 BD518 is probably between 34.084 to 76.215 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Rhode Island.

No Close Approaches

2015 BD518's orbit is 15.30 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

2015 BD518's orbit is determined by observations dating back to Dec. 16, 2011. It was last officially observed on Feb. 11, 2022. The IAU Minor Planet Center records 202 observations used to determine its orbit.

Accessibility and Exploration

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