Key Facts

Overview

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

Esclangona orbits the sun every 931 days (2.55 years), coming as close as 1.81 AU and reaching as far as 1.93 AU from the sun. Esclangona is about 8.2 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

The rotation of Esclangona has been observed. It completes a rotation on its axis every 3.25 days.

No Close Approaches

Esclangona's orbit is 0.85 AU from Earth's orbit at its closest point. This means that there is an 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

Esclangona's orbit is determined by observations dating back to Dec. 21, 1938. It was last officially observed on Feb. 5, 2020. The IAU Minor Planet Center records 2,049 observations used to determine its orbit.

Accessibility and Exploration

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