Adonis is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified Adonis as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
Adonis orbits the sun every 938 days (2.57 years), coming as close as 0.44 AU and reaching as far as 3.31 AU from the sun. Its orbit is highly elliptical. Adonis is about 0.6 kilometers in diameter, making it small in absolute terms, but larger than ~97% of asteroids, comparable in size to the Golden Gate Bridge.
Adonis's orbit is 0.01 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.
