Five years ago, astronomers were electrified to confirm the discovery of Comet C/2017 K2, more commonly known as Comet K2. At the time, it was believed to be one of the largest comets zooming across the universe, with a nucleus believed to be around 11 miles in diameter and a tail measuring a ginormous 500,000 miles long.
Comet K2 entered the inner solar system on June 25, and on July 14 it will make its closest approach to the Earth. According to Brian Koehler, a supervisor at the Treworgy Planetarium in Mystic, Connecticut, Comet K2’s journey has created an exceptional visual phenomenon.
