Overview
87024 (2000 JS66) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2000 JS66 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 JS66 orbits the sun every 478 days (1.31 years), coming as close as 0.97 AU and reaching as far as 1.42 AU from the sun. Based on its brightness and the way it reflects light, 2000 JS66 is probably between 0.477 to 1.067 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.
The rotation of 2000 JS66 has been observed. It completes a rotation on its axis every 28.20 hours.
Close Approaches
2000 JS66's orbit is 0.10 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.
2000 JS66 has 18 close approaches predicted in the coming decades:
