Key Facts

Overview

7874 (1991 BE) is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1991 BE as potentially hazardous because its orbit does not bring it close to Earth.

1991 BE orbits the sun every 1,530 days (4.19 years), coming as close as 2.16 AU and reaching as far as 3.04 AU from the sun. 1991 BE is about 12.2 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Cleveland, Ohio.

No Close Approaches

1991 BE's orbit is 1.28 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.

Images and Observations

1991 BE's orbit is determined by observations dating back to Jan. 10, 1953. It was last officially observed on June 23, 2023. The IAU Minor Planet Center records 2,891 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
