Frequently asked questions
Is 2026 SA17 going to hit Earth?
No impact is predicted. 2026 SA17 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 SA17?
2026 SA17 is estimated at about 22 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 SA17 have?
2026 SA17 is APO object. It orbits the Sun once every 4.69 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 SA17 through a telescope?
Most of the time 2026 SA17 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.
