Key Facts

  • Categorized as a Apollo-class Asteroid
  • Comparable in size to a football field
  • Will pass within 4,088,175 km of Earth in 2021
  • Classified as a Near Earth Asteroid (NEA)
  • Classified as a Potentially Hazardous Asteroid (PHA)
  • See orbit simulation


2020 XU6 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2020 XU6 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2020 XU6 orbits the sun every 1,200 days (3.29 years), coming as close as 0.99 AU and reaching as far as 3.43 AU from the sun. Based on its brightness and the way it reflects light, 2020 XU6 is probably between 0.168 to 0.375 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2020 XU6'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.

2020 XU6 has 3 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Feb. 22, 2021 4,088,175 8.367
Jan. 31, 2054 29,428,777 13.771
Feb. 28, 2077 1,752,496 7.992
