5131 (1990 BG)

Key Facts

• Categorized as a Apollo-class Asteroid
• Comparable in size to the island of Manhattan
• Classified as a Near Earth Asteroid (NEA)
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

5131 (1990 BG) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1990 BG 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.

1990 BG orbits the sun every 662 days (1.81 years), coming as close as 0.64 AU and reaching as far as 2.33 AU from the sun. Based on its brightness and the way it reflects light, 1990 BG is probably between 2.835 to 6.339 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the island of Manhattan.

The rotation of 1990 BG has been observed. It completes a rotation on its axis every 37.20 hours.

1990 BG's spectral type None (Tholen) / S (SMASSII) indicates that it is likely to contain and .

No Close Approaches

1990 BG's orbit is 0.28 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

1990 BG's orbit is determined by observations dating back to Dec. 6, 1978. It was last officially observed on March 1, 2022. The IAU Minor Planet Center records 2,066 observations used to determine its orbit.
