Frequently asked questions
How close does 2026 TK4 come to Earth?
Its next notable close approach is on 2026-Oct-08, when it passes about 10.4 lunar distances from Earth — roughly 3,981,260 km. 2026 TK4 is currently about 12 lunar distances away — the live orbit and distance are shown above.
Is 2026 TK4 going to hit Earth?
No impact is predicted. 2026 TK4 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 TK4?
2026 TK4 is estimated at about 14 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 TK4 have?
2026 TK4 is APO object. It orbits the Sun once every 1.84 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 TK4 through a telescope?
Most of the time 2026 TK4 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.
