Surveys catalogue new near-Earth asteroids almost every night. The objects above were discovered within roughly the last year and have a close approach coming up — fresh finds whose orbits are still being refined. Provisional names (like 2026 MK2) encode the discovery year in their first four digits.
Newly found objects sometimes appear briefly on the impact-monitoring list while their orbits are uncertain, then drop off as more observations come in. Watch them pass on the close-approach calendar.
Frequently asked questions
How are new near-Earth asteroids discovered?
Automated sky surveys image the same patches of sky repeatedly and flag anything that moves against the stars. New objects get a provisional designation encoding the discovery year, then their orbit is refined as more observations accumulate.
Why do newly discovered asteroids sometimes look risky at first?
With only a few days of observations, an orbit has large uncertainty, so a wide range of future paths — including very distant Earth approaches — can’t yet be ruled out. As tracking continues the uncertainty collapses and almost all are cleared.
