Frequently asked questions
How close does 2023 SZ3 come to Earth?
Its next notable close approach is on 2026-Sep-16, when it passes about 6.7 lunar distances from Earth — roughly 2,574,245 km. 2023 SZ3 is currently about 10 lunar distances away — the live orbit and distance are shown above.
Is 2023 SZ3 going to hit Earth?
No impact is predicted. 2023 SZ3 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 2023 SZ3?
2023 SZ3 is estimated at about 58 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 2023 SZ3 have?
2023 SZ3 is APO object. It orbits the Sun once every 1.50 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 2023 SZ3 through a telescope?
Most of the time 2023 SZ3 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.
