The comet was first visible to stargazers in the Northern Hemisphere at the beginning of the month followed by the other half of the planet a few weeks later. During that time, the comet will be 26 million miles away from the planet, according to astronomers. NASA scientists said the comet made its closest approach to the sun, or perihelion, on Jan.

“In the comet business, you just wait for the next one because there are dozens of these," Chodas said. And if you miss it Wednesday, you can try for a couple more weeks before it's gone. This deep-freeze haven for comets is believed to stretch more than one-quarter of the way to the next star. [comet C/2022 E3 (ZTF)](https://www.space.com/comet-c2022-e3-ztf-portugal-photo), which last passed through the inner solar system around 50,000 years ago, will be at its brightest during this time and may even be visible to the naked eye under the right conditions," according to [Space.com](https://www.space.com/comet-c2022-e3-ztf-closest-approach-feb-1). Another wild card: jets of dust and gas streaming off the comet as it heats up near the sun. While comet ZTF originated in our solar system, we can't be sure it will stay there, Chodas said. It's made up of ice with a gas tail, containing compounds that give it its green hue by reflecting light, according to NASA scientists. 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.

A green comet called C/2022 E3 (ZTF), or Comet ZTF for short, is nearing its closest approach to Earth for the first time since the ice age.

The reason why it's so difficult to study this phenomenon on Earth is because C2 is so unstable. But the Universe likes order, so the molecule will do everything it can to return to its neutral state. But it was only in 2021 that a team, led by Schmidt, A comet is essentially a galactic snowball – it's a body made of ice and dust.

What that means is that the molecule can absorb some of the light from the sun, in the form of a photon, to put it in an excited state.

10, and then slowly disappear from the night sky, likely not returning to our Solar System for millions of years. It will come through the orbits of Earth and Mars at a speed of approximately 128,500 miles per hour. Its nucleus is thought to be about a mile across, with its tails extending behind it by millions of miles.

C/2022 E3 (ZTF) comet is visible with the naked eye from certain locations on Tuesday night.

For a few weeks it will also be possible to see it using binoculars or a telescope. The comet made its closest approach to Earth in the early hours of 1 February, 2023. “On March 2nd, all we knew was that we had found a moving object. The green comet C/2022 E3 (ZTF) making its closest pass by Earth today originated from the Oort Cloud, a cosmic shell of debris encircling the farthest reaches of the Solar System. The early hours of 1 February will see Comet ZTF reach its perigee, meaning it is at its closest point to Earth, but it will still be visible with the naked eye for the next few days in case you don’t get a chance to see it tonight. At its perigee on Tuesday night and early Wednesday morning, the green comet had a brightness value of the magnitude of about +4.7, meaning it was possible to see it with the naked eye.

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.

A newly discovered comet will make its closest approach to our planet on Wednesday. Astronomers say the object's journey toward us took around 50,000 years.

But those expecting a brilliant streak of emerald in the sky will be disappointed. At that time the comet should appear just to the right of the pole star. Comets are mostly composed of ice and dust. The best time to view it will be in the early hours of Thursday morning when the Moon has set. The object originates in the Oort cloud, a collection of icy bodies at the edge of the Solar System. Its brightness is right at the threshold of what is visible to the naked eye.
