Sinon is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified Sinon as potentially hazardous because its orbit does not bring it close to Earth.
Sinon orbits the sun every 4,460 days (12.21 years), coming as close as 4.86 AU and reaching as far as 5.74 AU from the sun. Sinon is about 37.9 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Houston.
The rotation of Sinon has been observed. It completes a rotation on its axis every 8.14 days.
Sinon's orbit is 3.92 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.
Sinon's orbit is determined by observations dating back to March 24, 1955. It was last officially observed on Oct. 31, 2019. The IAU Minor Planet Center records 1,089 observations used to determine its orbit.
