Overview

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 0.441 to 0.986 kilometers in diameter, making it small in absolute terms, but larger than ~97% of 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 an wide berth between this asteroid and Earth at all times.

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