Sagan is a small asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Sagan as potentially hazardous because its orbit does not bring it close to Earth.
Sagan orbits the sun every 1,188 days (3.25 years), coming as close as 2.04 AU and reaching as far as 2.35 AU from the sun. Sagan is about 6.6 kilometers in diameter, making it larger than most asteroids, comparable in size to the San Francisco Bay.
The rotation of Sagan has been observed. It completes a rotation on its axis every 5.26 days.
Sagan's orbit is 1.04 AU from Earth's orbit at its closest point. This means that there is a 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.
Sagan's orbit is determined by observations dating back to Feb. 3, 1959. It was last officially observed on Sept. 18, 2018. The IAU Minor Planet Center records 1,916 observations used to determine its orbit.
