Cuno is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified Cuno as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
Cuno orbits the sun every 1,020 days (2.79 years), coming as close as 0.73 AU and reaching as far as 3.24 AU from the sun. Cuno is about 3.7 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.
The rotation of Cuno has been observed. It completes a rotation on its axis every 3.56 days.
Cuno's orbit is 0.03 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.
Cuno has 11 close approaches predicted in the coming decades:
