Rare green comet C/2022 E3 is about to make its closest approach to Earth


A commet named C/2022 E3  is believed to pass close to the earth's surface. 

Remember, Once this unknown comet leaves the  Earth’s neighbourhood, some observations have predicted  that it might be travelling so fast  that it will vanish by leaving the solar system altogether. or have its orbit bumped around by the gravity of the planets That's why it would not pass by again for millions of years. This may be the last chance to spot it.

One thing to know about this strange  comet, called C/2022 E3, is that it had spend most of it's time on solar system's outer most edges, in the  cloud named "Oort cloud" , but remember the prediction of its closest pass  is on 2 February.

Also read: Earth received a radio signal sent from a galaxy nine billion light years away.

This closest  pass which is going to happen on 2 february will bring the said comet within about 45 million kms of Earth, which is about 120 times the distance between our blue planet Earth and it's shining moon or about one-fifth the average distance to planet Mars.  Important thing to know about this comet is that It only orbits around the sun once in every 50,000 years or so. so that means its last travelling by our home planet was in the Stone Age, when humans ( Homosapeins) still coexisted with Neanderthals.

 Now the question is, how was it possible for early humans to saw it without any technological support. They would be spotting in the northern hemisphere areas with little light pollution. Just east of the little dipper, near the constellation of  Bo├Âtes  , it may be visible to the naked eye on February 1 and 2. Using a telescope, binoculars, or a camera with the long exposure option, it is expected to remain visible until mid-Moon before disappearing towards the Oort Cloud.

C/2022 E3 was first discovered by astronomers using the Zwicky Transient Facility in California in March  in the year 2022, and plunged beyond the orbit of Jupiter into the solar system. Its coma, the cloud of gas surrounding the comet's body or nucleus, appears green because of the carbon gas. But it's not just carbon. A relatively rare type called diatomic carbon, which is made up of two carbon atoms bonded together.


This is not the first time that we heard about any comet passing close to our beautiful blue planet "Earth". we keep hearing continuously  about such events through our great space agencies like NASA, ESA, JAXA and others. These events help us a lot in understanding this beautiful universe and make us knowledgeable more and more.
