Eboshi

Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to the city of Boston (10.88 km diameter)
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

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

Eboshi orbits the sun every 1,970 days (5.39 years), coming as close as 2.67 AU and reaching as far as 3.48 AU from the sun. Eboshi is about 10.9 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Boston.

The rotation of Eboshi has been observed. It completes a rotation on its axis every 48.76 hours.

No Close Approaches

Eboshi's orbit is 1.68 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

Eboshi's orbit is determined by observations dating back to Oct. 26, 1989. It was last officially observed on April 19, 2023. The IAU Minor Planet Center records 2,022 observations used to determine its orbit.
