Euler

Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to the city of Denver (19.77 km diameter)
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

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

Euler orbits the sun every 1,370 days (3.75 years), coming as close as 2.25 AU and reaching as far as 2.59 AU from the sun. Euler is about 19.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Denver.

The rotation of Euler has been observed. It completes a rotation on its axis every 5.99 hours.

No Close Approaches

Euler's orbit is 1.25 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

Euler's orbit is determined by observations dating back to April 17, 1942. It was last officially observed on Feb. 17, 2023. The IAU Minor Planet Center records 3,986 observations used to determine its orbit.
