Vishnu is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified Vishnu as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
Vishnu orbits the sun every 398 days (1.09 years), coming as close as 0.59 AU and reaching as far as 1.53 AU from the sun. Vishnu is about 0.4 kilometers in diameter, making it small in absolute terms, but larger than 90% of asteroids, comparable in size to the U.S. Capitol building.
Vishnu's orbit is 0.02 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.
Vishnu has 13 close approaches predicted in the coming decades:
