5828 (1991 AM) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1991 AM 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.
1991 AM orbits the sun every 808 days (2.21 years), coming as close as 0.52 AU and reaching as far as 2.88 AU from the sun. 1991 AM is about 1.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. Pentagon.
The rotation of 1991 AM has been observed. It completes a rotation on its axis every 2.67 hours.
1991 AM's orbit is 0.40 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.
1991 AM's orbit is determined by observations dating back to Nov. 13, 1982. It was last officially observed on Feb. 7, 2021. The IAU Minor Planet Center records 830 observations used to determine its orbit.
