8638 (1986 QY) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1986 QY as potentially hazardous because its orbit does not bring it close to Earth.
1986 QY orbits the sun every 1,660 days (4.54 years), coming as close as 2.33 AU and reaching as far as 3.14 AU from the sun. Based on its brightness and the way it reflects light, 1986 QY is probably between 5.788 to 12.943 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.
1986 QY's orbit is 1.35 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.
1986 QY's orbit is determined by observations dating back to Aug. 26, 1986. It was last officially observed on Nov. 28, 2022. The IAU Minor Planet Center records 2,608 observations used to determine its orbit.
