188174 (2002 JC) is a mid-sized asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2002 JC 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 JC orbits the sun every 271 days (0.74 years), coming as close as 0.50 AU and reaching as far as 1.14 AU from the sun. Based on its brightness and the way it reflects light, 2002 JC is probably between 0.880 to 1.968 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. Pentagon.
The rotation of 2002 JC has been observed. It completes a rotation on its axis every 2.47 days.
2002 JC's orbit is 0.09 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.
2002 JC has 15 close approaches predicted in the coming decades:
