Key Facts

Overview

2019 MO is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2019 MO 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.

2019 MO orbits the sun every 1,470 days (4.02 years), coming as close as 0.94 AU and reaching as far as 4.11 AU from the sun. Based on its brightness and the way it reflects light, 2019 MO is probably between 0.004 to 0.009 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

No Close Approaches

2019 MO's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is very close to Earth's orbit.

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

Images and Observations

2019 MO's orbit is determined by observations dating back to June 22, 2019. It was last officially observed on June 22, 2019. 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.
