C/2017 K2 PanSTARRS: According to Astronomers Comet K2 will be visible from Earth

A new comet will enter the inner solar system in the next few days and will be visible from Earth as well. It was discovered by astronomers when it was still far from Earth. The comet, known as C/2017 K2 or simply "K2," was discovered for the first time by the Hubble Space Telescope in May 2017, according to the US space agency NASA. K2 is a recent arrival in our area. Comet K2 has just made its maiden entry into the inner Solar System from the far-off Oort Cloud. When it was first found in May 2017, it was about 2.4 billion kilometers from the Sun, between Uranus and Saturn. This made it the farthest active comet ever found.

The astronomers at the time determined that the core had a diameter of roughly 18 kilometers. The diameter of the object is currently believed to be between 15 and 80 kilometers, but further ground-based telescope observations eventually did not yield a consistent conclusion. As a result, the only thing that is certain is that the object is rather enormous. Of course, the gas and dust trails will be much greater. The largest planet in the solar system, Jupiter, has a diameter of up to six times this, or 800,000 kilometers, according to scientific estimations. Due to the huge distances in space, the nucleus, despite its size, can hardly be observed by average interested parties on Earth. However, this is obviously achievable with the large tail.

On the night of July 14, K2 will be the closest to the planet. Even so, it will probably be challenging to see it with the unaided eye, if only because the full moon the day before made the night sky so brilliant. Here, even a tiny telescope is really helpful. A smartphone astronomy app that directs the observer to the proper position is the best way to determine precisely where it can be seen in the sky. It won't matter if there isn't a chance to see the comet that particular night. The object will be visible in the sky from Earth by September.

What is C/2017 K2 (PanSTARRS)? 

The comet appears to have come from the Oort cloud, which is thought to be a collection of ice and rocks beyond the boundary of our solar system, far beyond the last of the planets. We can only assume that the Oort cloud exists because the fragments are too faint to be seen, even with the James Webb telescope (but it's a reasonably educated estimate, so there's no need to become an Oort cloud believer). One of these chunks will periodically be coaxed by the sun's gravity out of the Oort cloud and into our general vicinity, at which point the show begins.

Even though C/2017 K2 (PanSTARRS) doesn't look like it will be one of these cosmic attention-getters any time soon, comets can sometimes be seen with the naked eye when the sun's rays cause them to release gases that make them glow. But the K2 comet stands out because, unlike other comets, it appears to be entering our inner solar system for the first time. This is unlike other comets, which appear repeatedly. Considering that it would take a lot of gas to get rid of it, its strange state seems to have made its gaseous halo bigger and brighter.

C/2017 K2: Does that mean that this comet is approaching Earth?

According to our research, internet users looking for information about this comet are also checking to see if it will kill us all. This could be because they just finished watching a Leonardo DiCaprio film about the subject. Relax in the short response to that question. There is absolutely no chance that this comet will hit the planet. The Panoramic Survey Telescope and Rapid Response System (PanSTARRS), located in Hawaii, made the find in 2017. As one of Earth's watching sentinels, PanSTARRS ensures that no dangerous "near-Earth objects" catch us off guard. But this was never indicated as a possible risk. Also, as I said before, it is moving away from us right now instead of toward us.

C/2017 K2: So how do I see this comet?

If you're just starting out, some trial and error may be necessary. If you can view the comet with your new telescope on the first night, you'll be extremely lucky. Learn to locate the serpent-bearer constellation Ophiuchus by starting on any night when you can see the stars. The comet will appear as a small speck in this constellation when you find it. Utilizing the interactive sky map on Skyandtelescope.org, you can practice this at home using your computer. You should be able to locate the star cluster IC 4665 in Ophiuchus with the use of an even more thorough star chart. Look for a cluster that, with a little bit of squinting, sort of resembles the word "Hi"; that is IC 4665.
