Key Facts


Elatus is a large asteroid with an orbit between Jupiter and Neptune. NASA JPL has not classified Elatus as potentially hazardous because its orbit does not bring it close to Earth.

Elatus orbits the sun every 14,700 days (40.25 years), coming as close as 7.22 AU and reaching as far as 16.28 AU from the sun. Elatus is about 57.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Rhode Island.

The rotation of Elatus has been observed. It completes a rotation on its axis every 26.82 hours.

No Close Approaches

Elatus's orbit is 6.22 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

Elatus's orbit is determined by observations dating back to Sept. 19, 1998. It was last officially observed on May 6, 2022. The IAU Minor Planet Center records 472 observations used to determine its orbit.

Accessibility and Exploration

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