Key Facts

Overview

19613 (1999 OX) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1999 OX as potentially hazardous because its orbit does not bring it close to Earth.

1999 OX orbits the sun every 1,680 days (4.60 years), coming as close as 2.48 AU and reaching as far as 3.05 AU from the sun. Based on its brightness and the way it reflects light, 1999 OX is probably between 4.411 to 9.864 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.

No Close Approaches

1999 OX's orbit is 1.50 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.

Images and Observations

1999 OX's orbit is determined by observations dating back to Nov. 25, 1986. It was last officially observed on Nov. 21, 2022. The IAU Minor Planet Center records 2,285 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
