2013 QC11

Its next notable close approach is on 2026-Aug-13, when it passes about 14.4 lunar distances from Earth — roughly 5,543,552 km. 2013 QC11 is currently about 257 lunar distances away — the live orbit and distance are shown above.

No impact is predicted. 2013 QC11 is classified as a potentially hazardous asteroid, which means its orbit brings it relatively close to Earth — but classification is about proximity, not an impending collision. Its trajectory is continuously refined as new observations are gathered, and predicted close approaches are calculated decades ahead. Its live position and orbit are shown above.

2013 QC11 is estimated at about 172 m across — comparable to the Eiffel Tower’s height. Size estimates are derived from how bright the asteroid appears and refined by radar and thermal measurements when it passes close to Earth.

2013 QC11 is APO object. It orbits the Sun once every 1.86 years, on an elliptical path that reaches beyond Earth’s orbit and swings back toward the Sun. The interactive orbit diagram above shows where it is right now.

Most of the time 2013 QC11 is far too faint to see, but during a close approach it can brighten enough for amateur telescopes. Check the close-approach date above, then plan your night with our sky and space-weather tools.
