Overview
2017 DA36 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2017 DA36 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.
2017 DA36 orbits the sun every 490 days (1.34 years), coming as close as 0.89 AU and reaching as far as 1.54 AU from the sun. Based on its brightness and the way it reflects light, 2017 DA36 is probably between 0.017 to 0.074 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
Close Approaches
2017 DA36'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.
2017 DA36 has 9 close approaches predicted in the coming decades:

Images and Observations
2017 DA36's orbit is determined by observations dating back to Feb. 16, 2017. It was last officially observed on March 11, 2017. The IAU Minor Planet Center records 137 observations used to determine its orbit.
Accessibility and Exploration
2017 DA36 can be reached with a journey of 370 days. This trajectory would require a delta-v of 8.674 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 10,662 potential trajectories and launch windows to this asteroid.
