Overview
Agni is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified Agni as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
Agni orbits the sun every 294 days (0.80 years), coming as close as 0.63 AU and reaching as far as 1.10 AU from the sun. Agni is about 0.5 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 Agni has been observed. It completes a rotation on its axis every 21.99 hours.
Close Approaches
Agni'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.
Agni has 21 close approaches predicted in the coming decades:
