Key Facts

Overview

18089 (2000 JB41) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 2000 JB41 as potentially hazardous because its orbit does not bring it close to Earth.

2000 JB41 orbits the sun every 1,310 days (3.59 years), coming as close as 1.76 AU and reaching as far as 2.94 AU from the sun. Based on its brightness and the way it reflects light, 2000 JB41 is probably between 2.527 to 5.650 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the island of Manhattan.

No Close Approaches

2000 JB41's orbit is 0.77 AU from Earth's orbit at its closest point. This means that there is a very 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

2000 JB41's orbit is determined by observations dating back to July 11, 1982. It was last officially observed on Feb. 2, 2023. The IAU Minor Planet Center records 1,647 observations used to determine its orbit.

Accessibility and Exploration

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