Long-term impact monitoring
2026 MJ1 is tracked on the long-term monitoring list — here’s what the numbers actually mean.

Palermo scale

Possible dates tracked

A Torino rating of 0 means no cause for concern, and a Palermo value of -5.63 — below zero — means the chance is lower than the background risk of a similar random impact over the same period. The headline figure is a cumulative probability spread across 103 possible dates between 2067 and 2126, so the chance on any one date is far smaller still. No impact is predicted, and objects are routinely removed from monitoring as their orbits are refined — both Apophis and 2024 YR4 were.

Frequently asked questions
How close does 2026 MJ1 come to Earth?
Its next notable close approach is on 2026-Jun-30, when it passes about 1.5 lunar distances from Earth — roughly 581,722 km. 2026 MJ1 is currently about 4 lunar distances away — the live orbit and distance are shown above.
Is 2026 MJ1 going to hit Earth?
No impact is predicted. 2026 MJ1 is tracked on the long-term impact-monitoring list with a cumulative chance of roughly 1 in 15,269, spread across 103 possible dates between 2067 and 2126 — a very low probability. Its Torino rating is 0 (no hazard), and its Palermo value of -5.63 sits below the background level. Objects are removed from monitoring as their orbits are refined. The full impact-monitoring breakdown is shown above.
How big is 2026 MJ1?
2026 MJ1 is estimated at about 12 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 MJ1 have?
2026 MJ1 is APO object. It orbits the Sun once every 1.41 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 MJ1 through a telescope?
Most of the time 2026 MJ1 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.
