Overview

9058 (1992 JB) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1992 JB 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.

1992 JB orbits the sun every 709 days (1.94 years), coming as close as 1.00 AU and reaching as far as 2.12 AU from the sun. Based on its brightness and the way it reflects light, 1992 JB is probably between 0.693 to 1.549 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.

Close Approaches

1992 JB'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.

1992 JB has 6 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
April 21, 2025 15,291,069 11.669
April 11, 2060 25,120,610 8.970
April 18, 2093 12,994,751 10.275
April 24, 2126 16,666,728 11.995
April 14, 2161 22,135,943 9.161
April 20, 2194 12,394,421 10.432
