Green comet

Get your binoculars: The last time this recently discovered comet was this close to the sun, Neanderthals and mammoths walked the lands.

More than a fifth of them, including C/2022 E3 (ZTF), have been found since 2010. In the months since, astronomers also have found hints of the comet hiding in archival data, with its first known observation dating to October 25, 2021, according to [a database](https://ssd.jpl.nasa.gov/tools/sbdb_lookup.html#/?des=2022 E3) maintained by NASA’s Jet Propulsion Laboratory.

[Zwicky Transient Facility](https://www.ztf.caltech.edu/) (hence the “ZTF”), a wide-field camera at the Palomar Observatory in California that sweeps across the Northern Hemisphere’s night sky every two days, on the lookout for newly appearing objects such as comets and supernovae. In doing so, they would get an unprecedented glimpse at the surface of a primordial leftover of the solar system, largely untouched by the sun’s heat and glare. C/2022 E3 (ZTF) was found on March 2, 2022, by astronomers Frank Masci and Bryce Bolin. As telescopes have gotten bigger, data have gone digital, and computers have gotten better, astronomers have been able to spot objects in the night sky more easily, revolutionizing the study of asteroids, comets, and other small bodies within the solar system. The color of C/2022 E3 (ZTF) color isn’t unique: Most comets that have higher gas contents tend to yield C2, so they “are generally going to look green to our eye,” Knight says. [According to In-the-sky.org](https://in-the-sky.org/news.php?id=20230112_19_100), it made its closest approach to the sun on January 12, coming within 103 million miles (166 million km) of our home star. For the past several months, the recently discovered comet C/2022 E3 (ZTF) has been dazzling stargazers and astrophotographers, with the excitement ratcheting up in recent weeks. As the evening progresses, the comet’s position will appear to swivel counterclockwise relative to Polaris, along with the rest of the night sky. Knight recommends using a pair of binoculars or a small telescope to try and see the comet.

Discovered on March 2, 2022, by astronomers using the Zwicky Transient Facility's wide-field survey camera at the Palomar Observatory in San Diego County, California, the comet made its closest approach to the sun on Jan. 12, according to NASA.

“Despite traveling past our planet at nearly 40 kilometers per second, its distance from Earth means it appears stationary to the eye.

The green comet will make its closest approach to Earth in February 2023. Here's how NASA and earth sky enthusiasts can see it and get an epic image.

And then that allows me to take really long exposures and reveal a lot of detail in the night sky without getting like streaky stars, which is what happens normally when you don't have the star tracker because we're on a planet that's spinning," he explained. The star tracker fits on top of a tripod and allows astrophotographers to follow the stars. The dust tail tends to appear wider (more fan-like) and warmer in colour compared to the ion tail." The bright turquoise atmosphere of the comet, known as the coma, is also visible. "That's actually a good way to know that you're looking at the comet because it looks like a star surrounded by a turquoise glow." Or, as Gertsman noted, both of the comet's "tails."

Your best bet to see the comet will be between Wednesday and Thursday, Feb. Here’s my first effort at capturing the “Green Comet”, Comet c/2022 E3 (ZTF).

Langill says the rarity of such an event is still a cosmic thrill. 2, and Langill says, with clear skies and no light pollution, it should be easily seen by anyone willing to make a short drive outside the city. The sun heats up what astronomers describe as a giant “dirty snowball” and that, in turn, triggers a vast tail of dust and gas that can stretch millions of kilometres behind the glowing core.
