Key Facts

  • Categorized as a Apollo-class Asteroid
  • Comparable in size to the island of Manhattan (3.40 km diameter)
  • Will pass within 12,917,973 km of Earth in 2032
  • Classified as a Near Earth Asteroid (NEA)
  • Classified as a Potentially Hazardous Asteroid (PHA)

Midas is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified Midas as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

Midas orbits the sun every 865 days (2.37 years), coming as close as 0.62 AU and reaching as far as 2.93 AU from the sun. Midas is about 3.4 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.

The rotation of Midas has been observed. It completes a rotation on its axis every 5.22 hours.

Midas's spectral type None (Tholen) / V (SMASSII) indicates that it is likely to contain and .

Close Approaches

Midas's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

Midas has 9 close approaches predicted in the coming decades:
