Isis is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Isis as potentially hazardous because its orbit does not bring it close to Earth.
Isis orbits the sun every 1,390 days (3.81 years), coming as close as 1.90 AU and reaching as far as 2.99 AU from the sun. Isis is about 111.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Delaware.
The rotation of Isis has been observed. It completes a rotation on its axis every 13.59 days.
Isis's orbit is 0.90 AU from Earth's orbit at its closest point. This means that there is an 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.
Isis's orbit is determined by observations dating back to June 20, 1856. It was last officially observed on Feb. 3, 2020. The IAU Minor Planet Center records 2,886 observations used to determine its orbit.
Scientists have been able to determine this object's shape.
