US, WASHINGTON (ORDO NEWS) — The long-period comet C / 2019 Y4 was discovered on December 28, 2019. ATLAS got its second name in honor of the automated system of telescopes Asteroid Terrestrial-impact Last Alert System, thanks to which it was possible to detect a space object.
According to initial estimates, the period of revolution of the comet around the Sun was about five and a half thousand years. As close as possible to the Earth, C / 2019 Y4 (ATLAS) should in about a month – May 23. Initially, astronomers expected that by mid-May the comet could become extremely bright. But most likely this will not happen.
On April 20th, the Hubble Space Telescope made a detailed photo of the comet. The picture clearly shows that its core has decomposed into at least four fragments. Judging by the frame, the two brightest of them are also segmented – they consist of one or two bright and large, as well as an unclear amount of smaller and dull elements.
At the time of the survey, comet C / 2019 Y4 (ATLAS) was located at a distance of approximately 0.98 astronomical units (approximately 146 million kilometers) from Earth, and on May 23 it will approach 0.78 AU from our planet. (about 116 million kilometers).
Now a decaying comet with the help of a fairly large telescope (with a diameter of 15 centimeters or more) can be considered even by amateur astronomers. C / 2019 Y4 (ATLAS) moves in the constellation Giraffe and is visible throughout the night in good weather.
Earlier we wrote about how scientists were able to record the collision of black holes of significantly different masses, and a group of Polish astronomers announced that another comet, 2I \ Borisov, also gradually fell apart.
