Iris is a average-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Iris as potentially hazardous because its orbit does not bring it close to Earth.
Iris orbits the sun every 1,346 days (3.68 years), coming as close as 1.83 AU and reaching as far as 2.94 AU from the sun. Iris is about 199.8 kilometers in diameter, making it larger than most asteroids, comparable in size to the U.S. state of Maryland.
The rotation of Iris has been observed. It completes a rotation on its axis every 7.14 days.
Iris's orbit is 0.85 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.
Iris's orbit is determined by observations dating back to Aug. 23, 1848. It was last officially observed on Aug. 19, 2019. The IAU Minor Planet Center records 5,206 observations used to determine its orbit.
Scientists have been able to determine this object's shape.
