488453 (1994 XD) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1994 XD as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
1994 XD orbits the sun every 1,310 days (3.59 years), coming as close as 0.62 AU and reaching as far as 4.06 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 1994 XD is probably between 0.375 to 0.840 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.
The rotation of 1994 XD has been observed. It completes a rotation on its axis every 2.74 hours.
1994 XD's orbit is 0.02 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.
1994 XD has 9 close approaches predicted in the coming decades:
