Viva Techno – The National Research and Innovation Agency, or Brin, said natural phenomena are very attractive to the public. is a rare occurrence and only occurs every few years or decades. One of these interesting and rare events is a comet passing by the Earth.
Comets are members of the Solar System that, like Earth, also orbit the Sun, on their way from the outer Solar System (outer solar system) for regions within the Solar System (inner solar system) just crossed the earth.
Brin researcher Abdul Rachman, as coordinator of the National Observatory Management Center (BPON) Kupang, East Nusa Tenggara, said comet C/2017 K2 (PanSTARRS) or K2 for short passed Earth.
The comet is believed to have come from a location in the outer Solar System 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.
“This comet passed closest to Earth on July 13, 2022, at a distance of about 2 times the Earth’s from the Sun. Currently, Comet K2 is moving towards its closest distance from the Sun, which is estimated to occur in December this year. , ”Abdul said in Jakarta, Monday, 25 July 2022.
He continued, because it belongs to the group of non-periodic comets, K2 does not regularly pass near Earth as do periodic comets such as Halley’s Comet which have a period of about 83 years, so it is not known whether it will come again. When will it pass by the earth?
Abdul revealed that K2 was discovered on May 21, 2017 by the Panoramic Survey Telescope located in Hawaii, United States (US) and a comet monitoring system called Rapid Response System (PanSTARRS). Object in the outermost part of the Solar System.
