Key Facts

Overview

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

Annekoupal orbits the sun every 1,260 days (3.45 years), coming as close as 2.06 AU and reaching as far as 2.51 AU from the sun. Based on its brightness and the way it reflects light, Annekoupal is probably between 2.695 to 6.026 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the island of Manhattan.

The rotation of Annekoupal has been observed. It completes a rotation on its axis every 13.32 hours.

No Close Approaches

Annekoupal's orbit is 1.08 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

Annekoupal's orbit is determined by observations dating back to March 26, 1992. It was last officially observed on June 24, 2023. The IAU Minor Planet Center records 3,319 observations used to determine its orbit.

Accessibility and Exploration

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