Its distance would be 2.8 million kilometers away. The comet is getting brighter as it moves closer to the inner solar system. He said that it was discovered beyond the orbit of Saturn and had nucleus of 18 km wide. Amity Dubai Satellite Ground Station and Programme Leader-Aerospace Engineering at Amity University Dubai Sarath Raj NS, Project Director, said that C/2017 K2 is currently visible in the Ophiucus constellation. It has been departing the Oort cloud in a hyperbolic orbit for around 3 million years. NASA said that the Oort Cloud is thought to surround the rest of the solar system in a massive spherical shell. It resembles a gigantic, thick-walled bubble made of frozen space debris that can be as large as mountains. According to Right ascension is the celestial equivalent of longitude on Earth, and declination is equivalent to geographic latitude and hour angle when projected onto the celestial sphere. Currently, comet C/2017 K2 has a visual magnitude of 10.77 with an eccentricity of 1.00040763 and an inclination of 87.54276196°.

Last month, we brought you One of the most distant active comets ever spotted Now, the comet is almost here, and it's an exciting time as the celestial object is one of the most distant 'active' comets ever discovered, Space.com published today. "It's kind of like being able to touch something from the beginning of the solar system," David Jewitt, an astronomer at the University of California, Los Angeles, told Space.com. "It's probably the most primitive thing in the inner solar system at this time." The mysterious comet was first discovered by the Panoramic Survey Telescope and Rapid Response System (PanSTARRS) in Hawaii in May 2017, and even at that distance, out between the orbits of Saturn and Uranus, it was emitting a powerful coma: a halo of gas that extended 80,000 miles (130,000 kilometers) into space. Researchers speculate that K2 must have been active for several years when that first image was taken as backward modeling indicates that the comet was already venturing through space and oozing gas some 35 AU from the sun. AU refers to the Earth's average distance from the sun: one AU measures about 93 million miles (150 million kilometers). What the scientists cannot understand is how the comet produced its coma. At the distances it has been traveling, the Sun's rays are not powerful enough to create such a halo. "At 35 AU from the sun, temperature is probably something like 40 degrees above absolute zero," Jewitt said. "So we know that water is as solid as rock t...

• The Comet C/2017 K2 was discovered in 2017, and at the time was the farthest • On July 14, Comet K2 will get as close to Earth as it will for millions of years, making it visible with small • Scientists are unsure of its size, but the comet could be Comet C/2017 K2 (PanSTARRS) could be one of the largest we’ve ever spotted. Now, it’s drawing closer and closer to At 172 million miles from Earth and nearing, Comet K2 can already be seen through small telescopes. The best views should come around mid-July, when the comet reaches its nearest point to Earth, but you could still catch a glimpse of it well into September as it continues a run toward the ☄️ You love the cosmos. So do we. First observed in 2017 by the Hawaiian-based The magnitude and behavior of Comet K2 isn’t fully known. This is a great starter telescope for kids and adults alike. Comets, made mostly of rock and ice, generally activate as they near the sun and the ice heats. Comet K2 is plenty active—likely from a mixture of nitrogen, carbon dioxide, carbon monoxide, and molecular oxygen. It created a tail, dubbed a coma, of dust and gas at least 81,000 miles in diameter, roughly the size of “K2 is so far from the sun and so cold, we know for sure that the activity—all the fuzzy stuff making it look like a comet—is not produced, as in other comets, by the evaporation of water and ice,” David Jewitt, a University of California, Los Angeles lead researcher, More Out-of-This-World Stories • Spaceflight Will Warm t...

The trouble comes because, as professional comet observer John Noonan told Space.com, the inherent brightness (or luminosity) of the comet is determined by its distance from our planet, as well as the amount of sunlight hitting its surface. Noonan, a researcher at Auburn University in Alabama, has studied When K2 was discovered in 2017 on its journey inward from the cold, distant "The activity of these comets from the Oort Cloud is difficult to predict, and rarely is the activity level increase of these comets accurately measured as they come into the inner solar system," Noonan said. Even if its activity were increasing, K2 will be rather far away during its closest approach to our sun. Distance determines how much light reflected from the dust coma makes it to our telescopes on Earth. Illustration showing a comet passing by Earth. (Image credit: Getty) On July 13's closest approach to our planet, Noonan said, the comet will be nearly two Even when K2 gets to its closest approach to the sun in December, it will remain beyond the orbit of Mars at 1.8 astronomical units. The poor distance and dust production together, he said, make K2's showing likely a poor one. "None of [these factors] line up for an excellent naked-eye apparition," he said. — — — Quanzhi Ye, an astronomer at the University of Maryland who specializes in comets, told Space.com that K2's closest approach to the sun in December will also be faint because the comet will be on the other side of the sun relati...

Caption Comet K2's Orbit This illustration shows the orbit of comet C/2017 K2 PANSTARRS (K2) on its maiden voyage into the solar system. The Hubble Space Telescope observed K2 when it was 1.5 billion miles from the Sun, halfway between the orbits of Saturn and Uranus. The observations revealed a fuzzy cloud of dust, called a coma, surrounding the icy visitor, evidence that the frozen comet is being warmed by the Sun and releasing material. K2 is the farthest active inbound comet ever observed. K2 has been traveling toward the Sun for millions of years from its home in the Oort Cloud, a spherical region at the edge of our solar system. The graphic shows the comet in its inbound journey, high above the plane of the major planets' orbits. The orbits of the giant planets, from Jupiter to Neptune, are also shown in the diagram. The farthest object from the Sun depicted here is the dwarf planet Pluto, which resides in the Kuiper Belt, a vast rim of primordial debris encircling our solar system. Credits Keywords • • • • • •

NASA: Gigantic 18-km wide killer Comet K2 has passed Mars and is now moving towards Earth Comet C/2017 K2 (PanSTARRS) has now entered the inner circle of the solar system after crossing Mars and is fast approaching Earth, says NASA. When will it come closest to the Earth and is there a chance of strike? Find out. Just one week ago, we got the confirmation on when we might be able to see the highly anticipated Comet C.2017 K2 (PanSTARRS), and NASA has revealed that its appearance is on schedule as it has just entered the inner solar system. The comet is bigger than the asteroids that wrought carnage on Earth previously. And now the comet has crossed planet Mars and the next on its visiting list is Earth. The comet, which is on its maiden trip to our solar system, has become an object of both fascination and fear as scientists are puzzled how a comet whose nucleus is 18-kilometers wide can still remain active. The fears largely emerge from wondering what if it were to crash into the Earth. Given that it is larger than the asteroid that killed dinosaurs, if that were to happen, humans won't stand a chance. So, when is it visiting the Earth and do we need to be afraid? Read on. Comet K2 is approaching the Earth after passing Mars On June 30, 2022, NASA posted an Further explaining its own analysis of the comet, NASA revealed details of the comet as well as the date when it comes closest to the Earth. It added, “Hubble Space Telescope observations indicated the comet had a larg...
