- Not a Potentially Hazardous Object
- See orbit simulation
Overview
9401 (1994 TS3) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1994 TS3 as potentially hazardous because its orbit does not bring it close to Earth.
1994 TS3 orbits the sun every 1,600 days (4.38 years), coming as close as 2.14 AU and reaching as far as 3.22 AU from the sun. 1994 TS3 is about 5.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.
The rotation of 1994 TS3 has been observed. It completes a rotation on its axis every 3.69 hours.
No Close Approaches
1994 TS3's orbit is 1.16 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
1994 TS3's orbit is determined by observations dating back to Oct. 13, 1994. It was last officially observed on June 24, 2023. The IAU Minor Planet Center records 3,584 observations used to determine its orbit.
