- Not a Near Earth Object
- Not a Potentially Hazardous Object
- See orbit simulation
Overview
13763 (1998 SO135) is a mid-sized asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified 1998 SO135 as potentially hazardous because its orbit does not bring it close to Earth.
1998 SO135 orbits the sun every 2,120 days (5.80 years), coming as close as 2.83 AU and reaching as far as 3.64 AU from the sun. Based on its brightness and the way it reflects light, 1998 SO135 is probably between 3.635 to 8.129 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.
No Close Approaches
1998 SO135's orbit is 1.84 AU from Earth's orbit at its closest point. This means that there is an extremely 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
1998 SO135's orbit is determined by observations dating back to Oct. 30, 1981. It was last officially observed on April 23, 2023. The IAU Minor Planet Center records 1,125 observations used to determine its orbit.
