• Classified as a Near Earth Asteroid (NEA)
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

137925 (2000 BJ19) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2000 BJ19 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.

2000 BJ19 orbits the sun every 536 days (1.47 years), coming as close as 0.31 AU and reaching as far as 2.28 AU from the sun. Its orbit is highly elliptical. 2000 BJ19 is about 1.4 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. Pentagon.

The rotation of 2000 BJ19 has been observed. It completes a rotation on its axis every 48.00 hours.

2000 BJ19's spectral type None (Tholen) / Q (SMASSII) indicates that it is likely to contain .

No Close Approaches

2000 BJ19'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 BJ19's orbit is determined by observations dating back to Dec. 7, 1953. It was last officially observed on April 9, 2023. The IAU Minor Planet Center records 2,121 observations used to determine its orbit.
