Frequently asked questions
How close does 2021 PF7 come to Earth?
Its next notable close approach is on 2026-Dec-26, when it passes about 15.5 lunar distances from Earth — roughly 5,943,691 km. 2021 PF7 is currently about 173 lunar distances away — the live orbit and distance are shown above.
Is 2021 PF7 going to hit Earth?
No impact is predicted. 2021 PF7 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 2021 PF7?
2021 PF7 is estimated at about 10 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 2021 PF7 have?
2021 PF7 is ATE object. It orbits the Sun once every 0.97 years, on an elliptical path that spends much of its time inside Earth’s orbit. The interactive orbit diagram above shows where it is right now.
Can I see 2021 PF7 through a telescope?
Most of the time 2021 PF7 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.
