Summary[edit]

Description	English: This Hubble Space Telescope image shows a fuzzy cloud of dust, called a coma, surrounding the comet C/2017 K2 PANSTARRS (K2), the farthest active comet ever observed entering the solar system. The image was taken in June 2017 by Hubble's Wide Field Camera 3.

Image title	This Hubble Space Telescope image shows a fuzzy cloud of dust,called a coma, surrounding the comet C/2017 K2 Pan-STARRS (K2),the farthest active comet ever observed entering the solar system.Hubble snapped images of K2 when the frozen visitor was 1.5 billionmiles from the Sun, just beyond Saturn's orbit. Even at that remotedistance, sunlight is warming the frigid comet, producing an80,000-mile-wide coma that envelops a tiny, solid nucleus.K2 has been traveling for millions of years from its home in theOort Cloud, a spherical region at the edge of our solar system.This frigid area contains at least 100 million comets, the icyleftovers from the formation of the solar system 4.6 billion yearsago. During the comet's inward journey, gravitational tugs from theplanets nudged it from its trajectory so that it is no longergravitationally bound to the Sun. After K2 makes its closestapproach to the Sun in 2022, it will leave the solar system forever.The image was taken in June 2017 by Hubble's Wide Field Camera 3.
