39565 (1992 SL) is a small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 1992 SL 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 SL orbits the sun every 769 days (2.11 years), coming as close as 1.09 AU and reaching as far as 2.19 AU from the sun. Based on its brightness and the way it reflects light, 1992 SL is probably between 0.582 to 1.300 kilometers in diameter, making it small in absolute terms, but larger than ~97% of asteroids, very roughly comparable in size to the Golden Gate Bridge.
1992 SL's orbit is 0.09 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.
1992 SL has 4 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|Sept. 13, 2053||13,932,591||5.715|
|Sept. 16, 2114||13,744,126||5.835|
|Sept. 3, 2154||29,283,983||7.152|
|Sept. 19, 2175||14,476,778||6.097|
1992 SL's orbit is determined by observations dating back to Dec. 9, 1950. It was last officially observed on April 8, 2019. The IAU Minor Planet Center records 353 observations used to determine its orbit.
