Key Facts

Overview

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

Ecoadachi orbits the sun every 1,660 days (4.54 years), coming as close as 2.16 AU and reaching as far as 3.34 AU from the sun. Ecoadachi is about 8.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

The rotation of Ecoadachi has been observed. It completes a rotation on its axis every 36.93 hours.

No Close Approaches

Ecoadachi's orbit is 1.18 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

Ecoadachi's orbit is determined by observations dating back to Jan. 26, 1982. It was last officially observed on April 26, 2023. The IAU Minor Planet Center records 3,005 observations used to determine its orbit.

Accessibility and Exploration

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