17418 (1988 RT12) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 1988 RT12 as potentially hazardous because its orbit does not bring it close to Earth.
1988 RT12 orbits the sun every 4,300 days (11.77 years), coming as close as 4.34 AU and reaching as far as 6.01 AU from the sun. 1988 RT12 is about 15.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Philadelphia.
The rotation of 1988 RT12 has been observed. It completes a rotation on its axis every 6.08 hours.
1988 RT12's orbit is 3.34 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.
1988 RT12's orbit is determined by observations dating back to Oct. 18, 1977. It was last officially observed on June 23, 2023. The IAU Minor Planet Center records 870 observations used to determine its orbit.
