Overview

90147 (2002 YK14) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2002 YK14 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.

2002 YK14 orbits the sun every 654 days (1.79 years), coming as close as 0.99 AU and reaching as far as 1.96 AU from the sun. Based on its brightness and the way it reflects light, 2002 YK14 is probably between 0.579 to 1.294 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

2002 YK14's orbit is 0.19 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.

2002 YK14 has 4 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Dec. 24, 2020 28,189,295 16.137
Dec. 25, 2054 28,874,248 16.905
Dec. 25, 2165 28,250,052 15.911
Dec. 26, 2199 28,168,761 16.710
