Key Facts

Overview

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

Emmasun orbits the sun every 1,370 days (3.75 years), coming as close as 2.03 AU and reaching as far as 2.80 AU from the sun. Emmasun is about 2.2 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to Mount Everest.

No Close Approaches

Emmasun's orbit is 1.05 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

Emmasun's orbit is determined by observations dating back to Dec. 4, 1997. It was last officially observed on June 27, 2023. The IAU Minor Planet Center records 1,495 observations used to determine its orbit.

Accessibility and Exploration

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