11386 (1998 TA18) is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1998 TA18 as potentially hazardous because its orbit does not bring it close to Earth.
1998 TA18 orbits the sun every 1,320 days (3.61 years), coming as close as 1.70 AU and reaching as far as 3.00 AU from the sun. 1998 TA18 is about 12.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Cleveland, Ohio.
The rotation of 1998 TA18 has been observed. It completes a rotation on its axis every 15.96 hours.
1998 TA18's orbit is 0.71 AU from Earth's orbit at its closest point. This means that there is a very 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.
1998 TA18's orbit is determined by observations dating back to Dec. 25, 1973. It was last officially observed on July 2, 2023. The IAU Minor Planet Center records 2,747 observations used to determine its orbit.
