Five years ago, it was found that the longest distance comet will finally fly over the earth

Science Fiction Network June 21 (Liu Yazhu) Recently, according to foreign media reports, the big comet C/2017 K2, which was found by Hubble Space Telescope five years ago, will be closest to the earth a few weeks later.

C/2017 K2 (Comet K2) Panxing Comet is a long -cycle comet found by the pan -star plan on May 21, 2017.The farthest active comet recorded.

It is reported that the comet K2 on July 14, local time in the United States, will be closest to us in the process of crossing the inner solar system. Although the comet is already large, it may be difficult to see the comet K2 without using a small telescope.

Astronomers speculate that the width of the comet is 18 ~ 161 kilometers, and the traces of the dust and gas of the comet tail are about 130,000 to 800,000 kilometers, of which 130,000 kilometers are about the diameter of a Jupiter.The comet's track is extremely long, and scientists speculate that this may be the only opportunity to see this comet within millions of years.
