Key Facts

Overview

Opites is a mid-sized asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified Opites as potentially hazardous because its orbit does not bring it close to Earth.

Opites orbits the sun every 4,390 days (12.02 years), coming as close as 4.85 AU and reaching as far as 5.65 AU from the sun. Based on its brightness and the way it reflects light, Opites is probably between 7.388 to 16.521 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.

No Close Approaches

Opites's orbit is 3.96 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

Opites's orbit is determined by observations dating back to Sept. 10, 1996. It was last officially observed on Feb. 19, 2023. The IAU Minor Planet Center records 432 observations used to determine its orbit.

Accessibility and Exploration

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