7764 (1991 AB) is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1991 AB as potentially hazardous because its orbit does not bring it close to Earth.
1991 AB orbits the sun every 1,590 days (4.35 years), coming as close as 2.14 AU and reaching as far as 3.20 AU from the sun. 1991 AB is about 14.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Cleveland, Ohio.
1991 AB's orbit is 1.19 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.
1991 AB's orbit is determined by observations dating back to Jan. 7, 1991. It was last officially observed on June 26, 2023. The IAU Minor Planet Center records 2,831 observations used to determine its orbit.
