A Torino rating of 0 means no cause for concern, and a Palermo value of -3.86 — 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 8 possible dates between 2026 and 2094, 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
Is 2010 ER12 going to hit Earth?
No impact is predicted. 2010 ER12 is tracked on the long-term impact-monitoring list with a cumulative chance of roughly 1 in 751,032,670, spread across 8 possible dates between 2026 and 2094 — a very low probability. Its Torino rating is 0 (no hazard), and its Palermo value of -3.86 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 2010 ER12?
2010 ER12 is estimated at about 220 m across — comparable to the Eiffel Tower’s height. 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 2010 ER12 have?
2010 ER12 is AMO object. It orbits the Sun once every 2.96 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 2010 ER12 through a telescope?
Most of the time 2010 ER12 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.
