Key Facts

Overview

Ehdita is a large asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified Ehdita as potentially hazardous because its orbit does not bring it close to Earth.

Ehdita orbits the sun every 2,860 days (7.83 years), coming as close as 2.79 AU and reaching as far as 5.10 AU from the sun. Ehdita is about 23.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Indianapolis.

The rotation of Ehdita has been observed. It completes a rotation on its axis every 40.00 hours.

No Close Approaches

Ehdita's orbit is 1.79 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

Ehdita's orbit is determined by observations dating back to Sept. 4, 1987. It was last officially observed on April 29, 2023. The IAU Minor Planet Center records 2,729 observations used to determine its orbit.

Accessibility and Exploration

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