Key Facts


2010 MZ112 is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2010 MZ112 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

2010 MZ112 orbits the sun every 496 days (1.36 years), coming as close as 0.59 AU and reaching as far as 1.87 AU from the sun. 2010 MZ112 is about 0.8 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, comparable in size to the Golden Gate Bridge.

No Close Approaches

2010 MZ112's orbit is 0.17 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.

Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.

Images and Observations

2010 MZ112's orbit is determined by observations dating back to June 23, 2010. It was last officially observed on June 24, 2010. The IAU Minor Planet Center records 7 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
