9970 (1992 ST1) is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1992 ST1 as potentially hazardous because its orbit does not bring it close to Earth.
1992 ST1 orbits the sun every 1,700 days (4.65 years), coming as close as 2.21 AU and reaching as far as 3.37 AU from the sun. 1992 ST1 is about 20.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Indianapolis.
The rotation of 1992 ST1 has been observed. It completes a rotation on its axis every 22.87 hours.
1992 ST1's spectral type None (Tholen) / Cb (SMASSII) indicates that it is likely to contain water, iron, nickel, cobalt, nitrogen, and ammonia.
1992 ST1's orbit is 1.20 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.
1992 ST1's orbit is determined by observations dating back to Nov. 11, 1955. It was last officially observed on June 9, 2023. The IAU Minor Planet Center records 3,612 observations used to determine its orbit.
