Key Facts

Overview

2015 DQ249 is a large asteroid with an orbit between Jupiter and Neptune. NASA JPL has not classified 2015 DQ249 as potentially hazardous because its orbit does not bring it close to Earth.

2015 DQ249 orbits the sun every 45,800 days (125.39 years), coming as close as 18.23 AU and reaching as far as 31.85 AU from the sun. Based on its brightness and the way it reflects light, 2015 DQ249 is probably between 16.016 to 35.813 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the city of Indianapolis.

No Close Approaches

2015 DQ249's orbit is 17.30 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 DQ249's orbit is determined by observations dating back to Feb. 17, 2015. It was last officially observed on Feb. 24, 2015. The IAU Minor Planet Center records 23 observations used to determine its orbit.

Accessibility and Exploration

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