Eger

Key Facts

• Categorized as a Apollo-class Asteroid
• Comparable in size to the U.S. Pentagon (1.50 km diameter)
• Classified as a Near Earth Asteroid (NEA)
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

Eger is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified Eger as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

Eger orbits the sun every 608 days (1.66 years), coming as close as 0.91 AU and reaching as far as 1.90 AU from the sun. Eger is about 1.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. Pentagon.

The rotation of Eger has been observed. It completes a rotation on its axis every 5.71 hours.

Eger's spectral type None (Tholen) / Xe (SMASSII) indicates that it is likely to contain iron, nickel, and cobalt.

No Close Approaches

Eger's orbit is 0.08 AU from Earth's orbit at its closest point. This means that there is a 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

Eger's orbit is determined by observations dating back to Jan. 21, 1982. It was last officially observed on June 16, 2022. The IAU Minor Planet Center records 7,800 observations used to determine its orbit.
