16964 (1998 RD59) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1998 RD59 as potentially hazardous because its orbit does not bring it close to Earth.
1998 RD59 orbits the sun every 1,640 days (4.49 years), coming as close as 2.47 AU and reaching as far as 2.96 AU from the sun. 1998 RD59 is about 9.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.
1998 RD59's orbit is 1.56 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.
1998 RD59's orbit is determined by observations dating back to March 5, 1978. It was last officially observed on June 24, 2023. The IAU Minor Planet Center records 3,550 observations used to determine its orbit.
