Overview

301964 (2000 EJ37) is a large asteroid whose orbit does not match any defined asteroid orbital class. NASA JPL has not classified 2000 EJ37 as potentially hazardous because its orbit does not bring it close to Earth.

2000 EJ37 orbits the sun every 3,630 days (9.94 years), coming as close as 1.36 AU and reaching as far as 7.88 AU from the sun. Its orbit is highly elliptical. 2000 EJ37 is about 10.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Boston.

No Close Approaches

2000 EJ37's orbit is 0.39 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

2000 EJ37's orbit is determined by observations dating back to March 3, 2000. It was last officially observed on Jan. 13, 2023. The IAU Minor Planet Center records 1,607 observations used to determine its orbit.

Accessibility and Exploration

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