Comet C/2017 K2, also called K2, is finally making its way toward Earth after the Hubble Space Telescope detected it in the outer spaces of the solar system in 2017. At that moment, K2 was deemed the farthest active comet ever sighted, although it was surpassed by a distant mega comet named Comet Bernardinelli-Bernstein last year. K2 is about to make its nearest approach to our planet on July 14th. The comet will be roughly 168 million miles from Earth.
K2 was already active when it was initially observed in 2017 between the orbits of Saturn and Uranus, approximately 1.49 billion miles from the sun, which, by comparison, is roughly 16 times farther away than the Earth is from the sun.
Primary observations indicated that the comet had a large nucleus and an enormous coma. While the Canada–France–Hawaii Telescope (CFHT) implied K2’s core could be between 18 and 100 miles wide, data from the Hubble Space Telescope inducetrated that it might be only 11 miles wide.
Viewers will be able to see the comet’s passage on Virtual Telescope Project’s live webcast, starting at 6:15 p.m. on July 14th. Viewers will also be able to watch it on Space.com because of the Virtual Telescope Project.
