396593 (2001 HC) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2001 HC 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.
2001 HC orbits the sun every 299 days (0.82 years), coming as close as 0.44 AU and reaching as far as 1.31 AU from the sun. Based on its brightness and the way it reflects light, 2001 HC is probably between 0.421 to 0.942 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to the Golden Gate Bridge.
2001 HC's orbit is 0.10 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.
2001 HC has 15 close approaches predicted in the coming decades:
