5913 (1990 BU) is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1990 BU as potentially hazardous because its orbit does not bring it close to Earth.
1990 BU orbits the sun every 1,530 days (4.19 years), coming as close as 2.11 AU and reaching as far as 3.09 AU from the sun. 1990 BU is about 10.9 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Boston.
The rotation of 1990 BU has been observed. It completes a rotation on its axis every 52.00 hours.
1990 BU's orbit is 1.11 AU from Earth's orbit at its closest point. This means that there is an extremely 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.
1990 BU's orbit is determined by observations dating back to Oct. 27, 1967. It was last officially observed on May 7, 2023. The IAU Minor Planet Center records 3,327 observations used to determine its orbit.
