2016 EM157 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2016 EM157 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.
2016 EM157 orbits the sun every 282 days (0.77 years), coming as close as 0.59 AU and reaching as far as 1.09 AU from the sun. Based on its brightness and the way it reflects light, 2016 EM157 is probably between 0.007 to 0.032 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2016 EM157's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
2016 EM157 has 9 close approaches predicted in the coming decades:

2016 EM157's orbit is determined by observations dating back to March 14, 2016. It was last officially observed on March 17, 2016. The IAU Minor Planet Center records 41 observations used to determine its orbit.
2016 EM157 can be reached with a journey of 354 days. This trajectory would require a delta-v of 11.992 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 1 potential trajectories and launch windows to this asteroid.
