Frequently asked questions
How close does 2026 RF15 come to Earth?
Its next notable close approach is on 2026-Sep-19, when it passes about 5.5 lunar distances from Earth — roughly 2,124,365 km. 2026 RF15 is currently about 21 lunar distances away — the live orbit and distance are shown above.
Is 2026 RF15 going to hit Earth?
No impact is predicted. 2026 RF15 is not on any impact-risk watchlist. 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.
How big is 2026 RF15?
2026 RF15 is estimated at about 27 m across — about the size of a house. Size estimates are derived from how bright the asteroid appears and refined by radar and thermal measurements when it passes close to Earth.
What kind of orbit does 2026 RF15 have?
2026 RF15 is APO object. It orbits the Sun once every 1.09 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.
Can I see 2026 RF15 through a telescope?
Most of the time 2026 RF15 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.
