See the Green Comet that Was Visible In the Sky Last Week



The Earth received a celestial visit this week in the form of Comet C / 2018 Y1 Iwamoto. This shimmering piece of ice and minerals in shades of green was visible in the night sky through telescopes and even binoculars.

This particular comet was only discovered a few months ago by amateur astronomer Masayuki Iwamoto - and the icy rock is calculated to take 1,371 years to orbit the Sun on a stretched elliptical path.




Here are some of the best images taken during the flyby…

Photo taken February 10. On Tuesday night, when the comet is closest to Earth at 28 million miles away, its movement will be even more noticeable.
