30791 (1988 RY11) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 1988 RY11 as potentially hazardous because its orbit does not bring it close to Earth.
1988 RY11 orbits the sun every 4,350 days (11.91 years), coming as close as 4.89 AU and reaching as far as 5.54 AU from the sun. 1988 RY11 is about 20.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Indianapolis.
1988 RY11's orbit is 3.94 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 RY11's orbit is determined by observations dating back to July 29, 1987. It was last officially observed on June 27, 2023. The IAU Minor Planet Center records 889 observations used to determine its orbit.
