Key Facts

  • Categorized as a Apollo-class Asteroid
  • Comparable in size to Mount Everest
  • Will pass within 25,837,124 km of Earth in 2064
  • Classified as a Near Earth Asteroid (NEA)
  • Not a Potentially Hazardous Object
  • See orbit simulation


Ubasti is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified Ubasti 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.

Ubasti orbits the sun every 772 days (2.11 years), coming as close as 0.88 AU and reaching as far as 2.42 AU from the sun. Based on its brightness and the way it reflects light, Ubasti is probably between 1.839 to 4.112 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.

Close Approaches

Ubasti's orbit is 0.17 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.

Ubasti has 3 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
March 4, 2064 25,837,124 24.014
March 4, 2138 26,692,577 22.886
March 7, 2157 29,291,683 25.075

Images and Observations

Ubasti's orbit is determined by observations dating back to Aug. 23, 1987. It was last officially observed on July 4, 2020. The IAU Minor Planet Center records 794 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
