37578 (1990 RY2) is a mid-sized asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified 1990 RY2 as potentially hazardous because its orbit does not bring it close to Earth.
1990 RY2 orbits the sun every 2,850 days (7.80 years), coming as close as 2.90 AU and reaching as far as 4.98 AU from the sun. Based on its brightness and the way it reflects light, 1990 RY2 is probably between 6.061 to 13.553 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.
1990 RY2's orbit is 1.89 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.
1990 RY2's orbit is determined by observations dating back to Aug. 11, 1951. It was last officially observed on Feb. 19, 2023. The IAU Minor Planet Center records 1,724 observations used to determine its orbit.
