Key Facts

Overview

54690 (2001 EB) is a mid-sized asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2001 EB 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.

2001 EB orbits the sun every 760 days (2.08 years), coming as close as 1.21 AU and reaching as far as 2.05 AU from the sun. Based on its brightness and the way it reflects light, 2001 EB is probably between 0.833 to 1.862 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the Golden Gate Bridge.

2001 EB's spectral type None (Tholen) / Sl (SMASSII) indicates that it is likely to contain and .

No Close Approaches

2001 EB's orbit is 0.41 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

2001 EB's orbit is determined by observations dating back to Dec. 14, 1952. It was last officially observed on May 5, 2022. The IAU Minor Planet Center records 396 observations used to determine its orbit.

Accessibility and Exploration

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