Atlantis is a small asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified Atlantis as potentially hazardous because its orbit does not bring it close to Earth.
Atlantis orbits the sun every 1,234 days (3.38 years), coming as close as 1.50 AU and reaching as far as 3.01 AU from the sun. Based on its brightness and the way it reflects light, Atlantis is probably between 3.669 to 8.204 kilometers in diameter, making it larger than most asteroids, very roughly comparable in size to the San Francisco Bay.
The rotation of Atlantis has been observed. It completes a rotation on its axis every 16.00 days.
Atlantis's orbit is 0.49 AU from Earth's orbit at its closest point. This means that there is an 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.
Atlantis's orbit is determined by observations dating back to Sept. 7, 1931. It was last officially observed on Aug. 22, 2019. The IAU Minor Planet Center records 1,603 observations used to determine its orbit.
