Key Facts

  • Categorized as a Aten-class Asteroid
  • Comparable in size to the Golden Gate Bridge
  • Will pass within 29,028,514 km of Earth in 2023
  • Classified as a Near Earth Asteroid (NEA)
  • Not a Potentially Hazardous Object
  • See orbit simulation


289227 (2004 XY60) is a small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2004 XY60 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.

2004 XY60 orbits the sun every 187 days (0.51 years), coming as close as 0.13 AU and reaching as far as 1.15 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2004 XY60 is probably between 0.435 to 0.973 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.

Close Approaches

2004 XY60's orbit is 0.19 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.

2004 XY60 has 9 close approaches predicted in the coming decades:
