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 larger than 90% of asteroids but tiny compared to large asteroids, comparable in size to the U.S. Capitol building.
The rotation of Vishnu has been observed. It completes a rotation on its axis every 44.40 hours.
Vishnu's orbit is 0.02 AU from Earth's orbit at its closest point. This means that there is a wide berth between this asteroid and Earth at all times.
Vishnu has 13 close approaches predicted in the coming decades:

Vishnu's orbit is determined by observations dating back to Aug. 2, 1986. It was last officially observed on Sept. 11, 2021. The IAU Minor Planet Center records 565 observations used to determine its orbit.
