31869 (2000 EF101) is a mid-sized asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified 2000 EF101 as potentially hazardous because its orbit does not bring it close to Earth.
2000 EF101 orbits the sun every 1,250 days (3.42 years), coming as close as 1.66 AU and reaching as far as 2.88 AU from the sun. 2000 EF101 is about 3.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.
2000 EF101's orbit is 0.66 AU from Earth's orbit at its closest point. This means that there is a very 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.
2000 EF101's orbit is determined by observations dating back to July 21, 1990. It was last officially observed on Jan. 29, 2023. The IAU Minor Planet Center records 2,892 observations used to determine its orbit.
