154347 (2002 XK4) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2002 XK4 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.
2002 XK4 orbits the sun every 919 days (2.52 years), coming as close as 0.57 AU and reaching as far as 3.13 AU from the sun. Based on its brightness and the way it reflects light, 2002 XK4 is probably between 1.624 to 3.631 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.
The rotation of 2002 XK4 has been observed. It completes a rotation on its axis every 3.32 hours.
2002 XK4's orbit is 0.27 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.
Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.
2002 XK4's orbit is determined by observations dating back to Feb. 22, 1998. It was last officially observed on April 13, 2023. The IAU Minor Planet Center records 854 observations used to determine its orbit.
