Key Facts

Overview

15737 (1991 CL) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1991 CL as potentially hazardous because its orbit does not bring it close to Earth.

1991 CL orbits the sun every 1,680 days (4.60 years), coming as close as 2.33 AU and reaching as far as 3.20 AU from the sun. 1991 CL is about 7.9 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

No Close Approaches

1991 CL's orbit is 1.36 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 CL's orbit is determined by observations dating back to April 11, 1950. It was last officially observed on May 30, 2023. The IAU Minor Planet Center records 3,324 observations used to determine its orbit.

Accessibility and Exploration

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