Frequently asked questions
How close does 2021 BJ3 come to Earth?
Its next notable close approach is on 2027-Feb-04, when it passes about 6.5 lunar distances from Earth — roughly 2,485,355 km. 2021 BJ3 is currently about 177 lunar distances away — the live orbit and distance are shown above.
Is 2021 BJ3 going to hit Earth?
No impact is predicted. 2021 BJ3 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 BJ3?
2021 BJ3 is estimated at about 34 m across — roughly the height of the Statue of Liberty. 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 BJ3 have?
2021 BJ3 is ATE object. It orbits the Sun once every 0.54 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 BJ3 through a telescope?
Most of the time 2021 BJ3 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.
