Overview

2016 AD193 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2016 AD193 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 AD193 orbits the sun every 698 days (1.91 years), coming as close as 0.55 AU and reaching as far as 2.53 AU from the sun. Based on its brightness and the way it reflects light, 2016 AD193 is probably between 0.193 to 0.431 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2016 AD193's orbit is 0.10 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.

2016 AD193 has 2 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
June 26, 2019 23,064,839 17.694
Jan. 15, 2035 27,452,557 25.017

Images and Observations

2016 AD193's orbit is determined by observations dating back to Jan. 13, 2016. It was last officially observed on June 28, 2019. The IAU Minor Planet Center records 38 observations used to determine its orbit.
