Overview
1994 EK is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1994 EK as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
1994 EK orbits the sun every 1,150 days (3.15 years), coming as close as 0.78 AU and reaching as far as 3.52 AU from the sun. Based on its brightness and the way it reflects light, 1994 EK is probably between 0.232 to 0.518 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.
Close Approaches
1994 EK's orbit is 0.03 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.
1994 EK has 8 close approaches predicted in the coming decades:
