Overview
2014 MK55 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2014 MK55 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2014 MK55 orbits the sun every 586 days (1.60 years), coming as close as 0.86 AU and reaching as far as 1.88 AU from the sun. Based on its brightness and the way it reflects light, 2014 MK55 is probably between 0.079 to 0.354 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.
Close Approaches
2014 MK55'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.
2014 MK55 has 18 close approaches predicted in the coming decades:

Images and Observations
2014 MK55's orbit is determined by observations dating back to June 29, 2014. It was last officially observed on Dec. 29, 2022. The IAU Minor Planet Center records 91 observations used to determine its orbit.
Accessibility and Exploration
2014 MK55 can be reached with a journey of 346 days. This trajectory would require a delta-v of 11.244 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 186 potential trajectories and launch windows to this asteroid.
