Key Facts

Overview

2010 DW47 is a small asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 2010 DW47 as potentially hazardous because its orbit does not bring it close to Earth.

2010 DW47 orbits the sun every 1,220 days (3.34 years), coming as close as 2.05 AU and reaching as far as 2.43 AU from the sun. Based on its brightness and the way it reflects light, 2010 DW47 is probably between 0.433 to 0.968 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.

No Close Approaches

2010 DW47's orbit is 1.04 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 DW47's orbit is determined by observations dating back to Sept. 23, 2008. It was last officially observed on Jan. 27, 2023. The IAU Minor Planet Center records 57 observations used to determine its orbit.

Accessibility and Exploration

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