Overview
26663 (2000 XK47) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2000 XK47 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2000 XK47 orbits the sun every 702 days (1.92 years), coming as close as 0.82 AU and reaching as far as 2.28 AU from the sun. Based on its brightness and the way it reflects light, 2000 XK47 is probably between 0.612 to 1.368 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.
The rotation of 2000 XK47 has been observed. It completes a rotation on its axis every 2.57 hours.
Close Approaches
2000 XK47's orbit is 0.04 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.
2000 XK47 has 6 close approaches predicted in the coming decades:
