437844 (1999 MN) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 1999 MN as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
1999 MN orbits the sun every 202 days (0.55 years), coming as close as 0.23 AU and reaching as far as 1.12 AU from the sun. Based on its brightness and the way it reflects light, 1999 MN is probably between 0.154 to 0.344 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.
The rotation of 1999 MN has been observed. It completes a rotation on its axis every 5.50 hours.
1999 MN's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
1999 MN has 56 close approaches predicted in the coming decades:
