Overview

52750 (1998 KK17) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1998 KK17 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.

1998 KK17 orbits the sun every 623 days (1.71 years), coming as close as 0.68 AU and reaching as far as 2.18 AU from the sun. 1998 KK17 is about 1.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the Golden Gate Bridge.

The rotation of 1998 KK17 has been observed. It completes a rotation on its axis every 26.43 hours.

Close Approaches

1998 KK17's orbit is 0.16 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.

1998 KK17 has 10 close approaches predicted in the coming decades:
