When comets heat up, the ice begins to sublimate or turn into a gas, which can give the comet a fuzzy appearance when looking at it through a telescope.įive takeaways from Trump’s CNN town hall The best viewing times are after the moon has set, just past midnight for those in the Northern Hemisphere.Ĭomets are frozen hunks of gas and ice that are known to carry the building blocks of life and are leftover bits from the formation of the solar system. C/2022 E3 (ZTF) appears green because the sunlight is interacting with carbon and cyanogen in the comet.ĭisney+, Hulu will become ‘one-app experience’ this year: CEOĬould AI be the future of preventing school shootings?
Best viewed with a telescope or binoculars, you can distinguish the comet from stars by the tail of dust and energized particles streaking behind it.Ĭomets get their colors by reflecting different hues of light based on their orbital positions and chemical compositions. Viewers will need darker skies to really spot the comet, with those in the Northern Hemisphere having the best view. It will appear as a faint green smudge visible in the sky near Polaris, the North star. The comet originates from the outer solar system and takes roughly 50,000 years to orbit the sun just once, so this is the only time to see this particular comet for a while. 1, 2023, before speeding away again, unlikely to return for millions of years. It is expected to come within 26 million miles (42 million kilometers) of Earth on Feb. It last visited during Neanderthal times, according to NASA. This photo provided by Dan Bartlett shows comet C/2022 E3 (ZTF) on Dec. The icy celestial object, discovered by astronomers Bryce Bolin and Frank Masci last year with the Zwicky Transient Facility telescope, will pass the Earth at a distance of 26 million miles (42 million kilometers), which is more than 100 times the distance from the Earth to the moon.
