Comet Tracker: Exactly Where To See The ‘Green Comet
Naked eye.When and where to see Comet ZTFDuring the latter part of January into early February, ZTF may become bright enough to be glimpsed with the naked eye. Use a reliable star map (or app) to track the night-by-night change in position relative to the background stars and constellations. Below are dates and approximate locations. We recommend going outside and looking northwest at approximately 9 pm local time (no matter where you are).January 12-14Look towards constellation Corona Borealis before sunrise from January 12-14.January 14-20Look towards constellation Boötes before sunrise from January 14-20.January 21The comet will be visible in the night sky (previously only visible in the early morning hours). Look north, above the Big Dipper—between the constellations Boötes and Draco—at approximately 9 pm local time on January 21. The new Moon on this night should make the comet easy to spot!Comet ZTF locations, courtesy of the MISAO Project.January 22-25Look north, Find the Big Dipper and look above, near the constellation Draco (The Dragon) from January 22-25.January 26-27Look to the left of the Big Dipper (several degrees to the east of the Little Dipper) on January 26. On the following night, look north, three degrees to the upper right of orange Beta Ursae Minoris (formerly known as Kochab), the brightest of the two outer stars in the Little Dipper’s bowl. We recommend 8-10 pm your local time.January 29-30Look north and find Polaris (the North Star) and look to east (to the right) on January 29-30 at approximately 9pm your local time.February 1Look near the constellation Camelopardalis on February 1. (Comet ZTF reaches its closest point to Earth on this day.)February 2-4Look between the constellations Camelopardalis and Auriga from February 2-4. (Although we don’t recommend trying to locate the green comet during these days due to the brightness of the full Moon.)February 5Look towards the brilliant yellow-white star Capella (in the constellation Auriga). We do not recommend looking for the green comet on this date due to the full Moon.February 6Look within the triangle known as “The Kids” star pattern in Auriga, directly overhead at around 8 pm your local time on

Update: The Green Comet (c/2022 e3 ZTF) otherwise known as Comet ZTF is currently traveling away from Earth and out of our solar system, never to return again. Your last (and best) chance to catch a glimpse will be on February 10. The full Moon will interfere until that time. (See below.)Learn more about upcoming sky events in our February Night Sky Guide.Published on January 12, 2023:Newly-discovered Comet ZTF is coming the closest to the Earth in 50,000 years, becoming visible to the unaided eye, and making big headlines. Some are calling it a “super rare” and “bright green” comet, but will it live up to the hype? We explain.Comet ZTF FactsComet ZTF was discovered in March 2022 by a wide field survey camera attached to a telescope known as Zwicky Transient Facility (ZTF) at the Palomar Observatory in Southern California (overseen by the Planetary Society). ZTF scans the entire northern sky every two days and captures hundreds of thousands of stars and galaxies in a single shot. Many comets have been found with this instrument. The most recent is catalogued as Comet c/2022 e3 ZTF, Comet ZTF for short.Why Is It Rare?Over the last 50,000 years, Comet ZTF has travelled a distance of 2.8 trillion miles and will make its closest approach to the Earth on Feb 1, 2023 (a distance of 26 million miles), according to Dan Bartlett/NASA. Orbital computations suggest that Comet ZTF may never return again.What Makes ZTF A Green Comet?The greenish color is likely due to a molecule made from two carbon atoms bonded together, called dicarbon. This unusual chemical process is confined chiefly to the head, not the tail. If you get a look at Comet ZTF, that greenish hue is likely to be quite faint (if it is visible at all). The appearance of green comets due to dicarbon is fairly uncommon.Recent images show the head (coma) appearing to be distinctly green and trailed by an impressively long thin blush appendage (the tail). But that is what a camera taking a long exposure sees. The tint will look much less green to theComet Tracker: Exactly Where To See The ‘Green Comet’

Visible right now after sunset in the west, comet Pons-Brooks—also known as 12P/Pons-Brooks—is about to reach its brightest and best – but it won’t last long.In fact, if you want to see it, you’d better get looking as soon as you can because the ball of rock and ice is about to depart from the northern sky.‘Devil Comet’Arriving in the wake of comet 2022 E3 (ZTF)—the so-called “green comet”—and 2020’s comet NEOWISE, it had been hoped that Pons-Brooks would be something of a “comet of the decade” and possibly be seen during totality at the recent total solar eclipse.That would have required an unpredictable outburst in brightness, something it had been observed to do back in July 2023 when its nucleus unexpectedly brightened. The halo of material around it expanded to possibly block some of it from view, causing a weird horned shape, earning it the nickname “devil comet.”How to find the comet during its perihelion this Sunday, April 21, 2024. StellariumPost-Sunset TargetHowever, despite not becoming a naked-eye object, the comet nevertheless makes a lovely target for anyone with binoculars. What’s more, it’s visible immediately after sunset.Comet Pons-Brooks is not particularly easy to find. This weekend, it reaches its perihelion—the closest it gets to the sun—causing it to look as bright as it will get. It will then make its closest approach to Earth on June 2.However, since it’s sinking lower towards the western horizon in the post-sunset night sky, it’s best to glimpse it before it’s too late.Gianluca Masi's images of comet 12P/Pons-Brooks from the Virtual Telescope Project facility in ...

When it approaches its closest point to our planet on Feb. 1, it won’t look as bright as a star, Gallagher noted. “It’s going to look like a small, fuzzy object — not a bright, pinpoint of light.”Marty McGuire, a NASA Solar System Ambassador from Bethlehem, Pennsylvania, agrees that casual observers shouldn’t get their hope up too high, because the comet might not get too bright and its orbit can be unpredictable as it moves closer to our hot sun.“The thing with comets is as they get closer, they could get demolished in a matter of minutes,” said McGuire, who is known in the Lehigh Valley as the “Backyard Astronomy Guy.”Because of its unpredictability, some experts say it might be a good idea for stargazers to grab a pair of binoculars or a small telescope and look for the green comet the next time the night sky is clear.A recently discovered comet known as Comet C/2022 E3 (ZTF) may be visible from Earth in January and February 2023, experts say. The green comet is expected to get brighter during the final weeks of January, but some experts say a telescope or binoculars may be needed to get the best view of this cosmic snowball.AP file photoWhen to see the green cometIf you live in the United States, or anywhere else in the northern hemisphere, the best time to look for the comet will be in the hours after midnight and before dawn, according to EarthSky.org and IGN.com.

Comets available to be viewed in tonight’s night sky. Most of these, however, are visible only with moderately large telescopes. You also would need a good star atlas as well as accurate coordinate positions in order to know where to point your instrument to actually see any of these. Most amateurs who make it a point to search them out call such comets “faint fuzzies” because that’s pretty much what they look like through the eyepiece: A faint, fuzzy blob of light. These are known as “common comets.” Every once in a while, perhaps two or three times over a span of 15 or 20 years, a bright or “great comet” will come along. These are the types that excite those of us without binoculars or telescopes—the type where all you need do is step outside, look up and exclaim: “Oh look at that!” Such comets tend to be much larger than average. Most of these have a core or nucleus less than two or three miles across. But there are others than can be up to several times larger.As a general rule, the closer a comet makes an approach to the Sun, the brighter it gets. Large ones that sweep closer than Earth’s distance from the Sun (92.9 million miles) tend to get quite bright. Good examples are Comet Hale-Bopp in the spring of 1997 and Comet NEOWISE (discovered with a robotic space telescope) in the summer of 2020.So which category does ZTF fall into? In many ways it’s pretty much a common comet, but compared to most of the other faint fuzzies, ZTF is extremely bright.Related ArticlesComets, Asteroids, And Meteors – The Difference Between ThemJanuary Night Sky GuideJoin The DiscussionWill you look to the sky for “green” comet ZTF?Let us know in the comments below!

This glowing celestial visitor is best seen in the predawn hours as it prepares to zoom safely past Earth. CAPE CANAVERAL, Fla. — A comet is streaking back our way after 50,000 years. The dirty snowball last visited during Neanderthal times, according to NASA. It will come within 26 million miles of Earth Wednesday before speeding away again, unlikely to return for millions of years. So do look up, contrary to the title of the killer-comet movie “Don’t Look Up.” Discovered less than a year ago, this harmless green comet already is visible in the northern night sky with binoculars and small telescopes, and possibly the naked eye in the darkest corners of the Northern Hemisphere. It's expected to brighten as it draws closer and rises higher over the horizon as January ends, best seen in the predawn hours. By Feb. 10, it will be near Mars, a good landmark. Skygazers in the Southern Hemisphere will have to wait until next month for a glimpse. While plenty of comets have graced the sky over the past year, “this one seems probably a little bit bigger and therefore a little bit brighter and it’s coming a little bit closer to the Earth’s orbit,” said NASA’s comet and asteroid-tracking guru, Paul Chodas. Green from all the carbon in the gas cloud, or coma, surrounding the nucleus, this long-period comet was discovered last March by astronomers using the Zwicky Transient Facility, a wide field camera at Caltech’s Palomar Observatory. That explains its official, cumbersome name: comet C/2022 E3 (ZTF). On Wednesday, it will hurtle between the orbits of Earth and Mars at a relative speed of 128,500 mph. Its nucleus is thought to be about a mile across, with its tails extending millions of miles. The comet isn’t expected to be nearly as bright as Neowise in 2020, or Hale-Bopp and Hyakutake in the mid to late 1990s. But "it will be bright by virtue of its close Earth passage ... which allows scientists to do more experiments and the public to be able to see a beautiful comet,” University of Hawaii astronomer Karen Meech said in an email. Scientists are confident in their orbital calculations putting the comet's last swing through the solar system's planetary neighborhood at 50,000 years ago. But they don't know how close it came to Earth or whether it was even visible to the Neanderthals, said Chodas, director of the Center for Near Earth Object Studies at NASA’s Jet Propulsion Laboratory in California. When it returns, though, is tougher to judge. Every time the comet skirts the sun and planets, their gravitational tugs alter the iceball’s path ever so slightly, leading to major course changes over time. Another wild card: jets of dust and gas streaming off the comet as it heats up near the sun. “We don’t really know exactly how much they are pushing this comet around,” Chodas said. The comet — a time capsule from the emerging solar system 4.5 billion years ago — came. Here's a green comet tracker.
