Bacchus is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified Bacchus 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.
Bacchus orbits the sun every 409 days (1.12 years), coming as close as 0.70 AU and reaching as far as 1.45 AU from the sun. Based on its brightness and the way it reflects light, Bacchus is probably between 0.922 to 2.061 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. Pentagon.
The rotation of Bacchus has been observed. It completes a rotation on its axis every 14.90 days.
Bacchus's orbit is 0.07 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.
