Key Facts

Overview

19033 (2157 P-L) is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 2157 P-L as potentially hazardous because its orbit does not bring it close to Earth.

2157 P-L orbits the sun every 2,080 days (5.69 years), coming as close as 2.72 AU and reaching as far as 3.66 AU from the sun. 2157 P-L is about 11.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Boston.

The rotation of 2157 P-L has been observed. It completes a rotation on its axis every 16.72 hours.

No Close Approaches

2157 P-L's orbit is 1.77 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

2157 P-L's orbit is determined by observations dating back to Sept. 24, 1960. It was last officially observed on Dec. 22, 2022. The IAU Minor Planet Center records 2,132 observations used to determine its orbit.

Accessibility and Exploration

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