Key Facts

  • Categorized as a Aten-class Asteroid
  • Comparable in size to the U.S. Capitol building
  • Classified as a Near Earth Asteroid (NEA)
  • Classified as a Potentially Hazardous Asteroid (PHA)
  • See orbit simulation


202683 (2006 US216) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2006 US216 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2006 US216 orbits the sun every 186 days (0.51 years), coming as close as 0.28 AU and reaching as far as 1.00 AU from the sun. Based on its brightness and the way it reflects light, 2006 US216 is probably between 0.291 to 0.652 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to the U.S. Capitol building.

No Close Approaches

2006 US216's orbit is 0.04 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

2006 US216's orbit is determined by observations dating back to Nov. 6, 2005. It was last officially observed on Jan. 7, 2017. The IAU Minor Planet Center records 89 observations used to determine its orbit.
