100624 (1997 TR28) is a mid-sized asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 1997 TR28 as potentially hazardous because its orbit does not bring it close to Earth.
1997 TR28 orbits the sun every 4,340 days (11.88 years), coming as close as 4.56 AU and reaching as far as 5.85 AU from the sun. Based on its brightness and the way it reflects light, 1997 TR28 is probably between 7.526 to 16.828 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.
The rotation of 1997 TR28 has been observed. It completes a rotation on its axis every 11.29 hours.
1997 TR28's orbit is 3.57 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.
1997 TR28's orbit is determined by observations dating back to Sept. 12, 1996. It was last officially observed on Jan. 24, 2023. The IAU Minor Planet Center records 990 observations used to determine its orbit.
