Key Facts

  • Categorized as a Apollo-class Asteroid
  • Comparable in size to a football field
  • Will pass within 27,215,632 km of Earth in 2020
  • Classified as a Near Earth Asteroid (NEA)
  • Not a Potentially Hazardous Object
  • See orbit simulation


2017 UP2 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2017 UP2 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.

2017 UP2 orbits the sun every 1,110 days (3.04 years), coming as close as 0.80 AU and reaching as far as 3.41 AU from the sun. Based on its brightness and the way it reflects light, 2017 UP2 is probably between 0.246 to 0.550 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to a football field.

Close Approaches

2017 UP2's orbit is 0.14 AU from Earth's orbit at its closest point. This means that there is a wide berth between this asteroid and Earth at all times.

2017 UP2 has 10 close approaches predicted in the coming decades:
