137805 (1999 YK5) is a mid-sized asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 1999 YK5 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.
1999 YK5 orbits the sun every 276 days (0.76 years), coming as close as 0.37 AU and reaching as far as 1.29 AU from the sun. 1999 YK5 is about 2.2 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to Mount Everest.
The rotation of 1999 YK5 has been observed. It completes a rotation on its axis every 3.93 days.
1999 YK5's orbit is 0.11 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.
1999 YK5 has 13 close approaches predicted in the coming decades:
