Ceres is a dwarf planet orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Ceres as potentially hazardous because its orbit does not bring it close to Earth.
Ceres orbits the sun every 1,680 days (4.60 years), coming as close as 2.55 AU and reaching as far as 2.98 AU from the sun. Ceres is about 939.4 kilometers in diameter, making it the largest asteroid/dwarf planet, comparable in size to the U.S. state of Alaska.
The rotation of Ceres has been observed. It completes a rotation on its axis every 9.07 hours.
Ceres's orbit is 1.59 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.
Ceres's orbit is determined by observations dating back to Jan. 5, 1995. It was last officially observed on Jan. 28, 2021. The IAU Minor Planet Center records 1,075 observations used to determine its orbit.
