Key Facts

  • Categorized as a Amor-class Asteroid
  • Comparable in size to the island of Manhattan (4.30 km diameter)
  • Classified as a Near Earth Asteroid (NEA)
  • Not a Potentially Hazardous Object
  • See orbit simulation

Overview

Tezcatlipoca is a small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified Tezcatlipoca as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

Tezcatlipoca orbits the sun every 816 days (2.24 years), coming as close as 1.09 AU and reaching as far as 2.33 AU from the sun. Tezcatlipoca is about 4.3 kilometers in diameter, making it larger than most asteroids, comparable in size to the island of Manhattan.

The rotation of Tezcatlipoca has been observed. It completes a rotation on its axis every 7.25 days.

Tezcatlipoca's spectral type SU (Tholen) / Sl (SMASSII) indicates that it is likely to contain magnesium silicate and iron silicate.

No Close Approaches

Tezcatlipoca's orbit is 0.25 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.

Images and Observations

Tezcatlipoca's orbit is determined by observations dating back to June 19, 1950. It was last officially observed on July 30, 2019. The IAU Minor Planet Center records 3,447 observations used to determine its orbit.

Scientists have been able to determine this object's shape.
