4953 (1990 MU) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1990 MU as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
1990 MU orbits the sun every 754 days (2.06 years), coming as close as 0.56 AU and reaching as far as 2.69 AU from the sun. Based on its brightness and the way it reflects light, 1990 MU is probably between 2.770 to 6.195 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the island of Manhattan.
The rotation of 1990 MU has been observed. It completes a rotation on its axis every 14.22 hours.
1990 MU's orbit is 0.03 AU from Earth's orbit at its closest point. This means that there is a wide berth between this asteroid and Earth at all times.
1990 MU has 11 close approaches predicted in the coming decades:
