Overview
2013 HO11 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2013 HO11 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.
2013 HO11 orbits the sun every 477 days (1.31 years), coming as close as 0.92 AU and reaching as far as 1.47 AU from the sun. Based on its brightness and the way it reflects light, 2013 HO11 is probably between 0.044 to 0.195 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
Close Approaches
2013 HO11's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
2013 HO11 has 13 close approaches predicted in the coming decades:

Images and Observations
2013 HO11's orbit is determined by observations dating back to April 4, 2013. It was last officially observed on Dec. 27, 2013. The IAU Minor Planet Center records 84 observations used to determine its orbit.
Accessibility and Exploration
2013 HO11 can be reached with a journey of 338 days. This trajectory would require a delta-v of 7.989 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 32,684 potential trajectories and launch windows to this asteroid.
