NASA: The 18-kilometer-wide giant killer comet K2 has crossed Mars and is now heading towards Earth

NASA says that comet C/2017 K2 (PanSTARRS) has now entered the inner circle of the solar system after crossing Mars and is rapidly approaching Earth. When will it come closest to Earth and is it likely to collide? trace.

Just a week ago, we got confirmation of when we’ll be able to see the much-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. has done The comet is larger than the asteroids that previously massacred Earth. And now the comet has crossed Mars and the next on the list is Earth. The comet, which is on its first visit to our solar system, has become a subject of both fascination and awe as scientists wonder how a comet whose nucleus is 18 kilometers wide can still remain active. The fear stems largely from thinking about what would happen if it crashes into the earth. Given that it’s bigger than the asteroid that killed the dinosaurs, if it were, humans wouldn’t have had a chance. So, when is it coming to Earth and do we need to be afraid? read on.

Comet K2 approaching Earth after passing through Mars

On June 30, 2022, NASA posted an image of Comet K2, saying “On its first visit to the inner Solar System from the dim and distant Oort cloud, this Comet PanSTARRS was initially observed five years ago, in May 2017. It was then the most distant active inbound comet ever discovered, when it was about 2.4 billion kilometers from the Sun, placing it between the orbital distances of Uranus and Saturn.

Further explaining its analysis of the comet, NASA revealed the details of the comet as well as the date when it came closest to Earth. It said, “Observations from the Hubble Space Telescope indicate that the comet had a large nucleus of less than 18 kilometers in diameter. Now visible in smaller telescopes, C/2017 K2 made its closest approach to planet Earth on July 14.” and will make its closest approach to the Sun this December. Its extended coma and developing tail are seen here at a distance of about 290 million kilometres, just 16 light-minutes away.

At this time, it is expected that the comet will make a safe flyby, although scientists are monitoring any changes in trajectory. Astronomy enthusiasts can see this comet fly by the Earth on July 14. It won’t be visible to the naked eye, but amateur telescopes will do just fine.
