2015 XW261 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2015 XW261 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.
2015 XW261 orbits the sun every 510 days (1.40 years), coming as close as 0.67 AU and reaching as far as 1.83 AU from the sun. Based on its brightness and the way it reflects light, 2015 XW261 is probably between 0.139 to 0.312 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2015 XW261's orbit is 0.12 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.
