Very rare! Comet K2 passes Earth, shows tail of dust and gas: OKZone Techno

comet C/2017 K2 (PanSTARRS) or abbreviated K2 Crossing Planet Earth. This is a very rare natural phenomenon, as it is not known when Comet K2 will pass through Earth again.

Abdul Rachman, a researcher at the National Research and Innovation Agency (BRIN) and coordinator of the Kupang National Observatory Management Agency (BPON), said that comet C/2017 K2 (PanSTARRS) originated from a location on the outskirts. The Solar System is called the Oort Cloud.

The comet’s initial C is non-periodic, the number 2017 indicates the year it was discovered, and the combination of letters and numbers K2 indicates the order in which it was discovered in 2017.

Abdul said, “This comet passed closest to Earth on July 13, 2022, at a distance of about 2 times the Sun from Earth. Currently K2 is moving towards its closest distance from the Sun, which is expected to happen in December this year. hopefully.” Rachman received in his official statement MNC PortalMonday (25/7/2022).

“Because it belongs to the non-periodic comet group, K2 does not regularly pass near Earth like periodic comets such as Halley’s Comet, which has a period of about 83 years, so it is not known whether it will pass near Earth again. When will it pass?” He added.

They revealed that K2 was discovered on May 21, 2017 by the Panoramic Survey Telescope based in Hawaii and a comet monitoring system called the Rapid Response System (PanSTARRS). The comet is believed to have originated from the Oort Cloud, a collection of objects. The outermost part of the solar system.

A tail of dust and gas is visible as Comet K2 passes closest to Earth. The closer to the sun, the gas tail will be more clearly visible.

“When passing close to Earth, K2 can only be seen with a telescope, especially because it coincides with the full moon. However, as the comet gets closer to the Sun, it will be visible with binoculars. On Earth’s surface Opportunity to see the comet on a clear night in all regions,” he said.

“We can see K2 for several months, especially as the comet passes near Earth, en route to its closest point to the Sun, and for several months thereafter,” he explained.

Abdul Rachman explained, through research related to the phenomenon of comet passing through the earth, the possibility of a comet falling to the earth can be studied.

In the case of K2, the comet passed Earth at a distance of more than 270 million kilometers so that it had no effect on Earth. Then because it passes far enough away from Earth, which is about 2 times Earth’s distance from the Sun, there is no negative effect.

“Comet K2 on BPON was observed for several days from July 13 to 16, 2022 at the Olansi Village Operations Office and Science Center. Observations were carried out for several hours every day. The data collected was not only for research purposes Can be analyzed, it can also be used for astrophotography,” he said.

“The observations are made using a telescope that measures 25 cm with a mirror and a CCD detector equipped with several color filters,” he explained.

Meanwhile, the head of the Center for Space Research, Emanuel Sunging, said the observational data could be used for research not only by BRAIN researchers, but by everyone interested in studying the dynamics of objects in the Solar System. can also be done.

“From the observable incarnations of the two comet tails (dust and gas), an understanding can be gained on the internal properties of the comet as well as what the space weather conditions were like at the time.”

“Furthermore, from the comet’s journey, until at least December 2022, it can be seen whether the comet ends its life after colliding with the Sun? Or continues its trajectory out of the solar system? Then how will it travel? ?” He continued.

The passing of K2 is a good opportunity for scientists to observe this comet more closely and for astrophotography workers to photograph it. Each comet has a peculiarity that is interesting to study scientifically and capture its presence through camera shots.

“The biggest hope from such small observations is to provide insight and information to Indonesians, that Indonesians already have an astronomical observatory in the East Nusa Tenggara region that can be used for space research with Brin ,” he concluded. ,
