The brightest comet of the year will welcome the opportunity to observe

Xinhua news agency, Tianjin, Dec. 9 (Reporter Zhou Rohan) Astronomical experts say the brightest comet in 2018 will spend the next day on the 12th and near the site of 16. If the weather is fine, atmospheric transparency is high enough , and the public interested in China With a small telescope, you can see it.

The comet is a small heavenly body in the solar system. The main component is water ice. Most of the comets are weak and bright enough to be seen with the naked eye. According to astronomical data, the comet is numbered with 46p / Wirtanen, which is a small short comet belonging to the common comet Musu. Often it is influenced by Jupiter's gravity and changes its orbit during the operation.

According to astronomical data, on January 17, 1948, US astronomers first discovered the comet's trajectory in a photographic film. Comet was once the target of the European Space Agency "Rosetta". Later, due to a missed window for detection, it was finally abandoned, and the glacier released by Rosetta successfully landed on another comet.

Shi Zichen, a member of the Chinese Astronomical Society and a member of the Astronomical Society Tianjin, said the 46th comet had passed the nearest point on the 12th place, and the closest place to the 16th, only 0.078 astronomical units of the country, which is 11.62 million kilometers, which is a comet 70 years ago. Closest to Earth from its discovery.

"This comet is very suitable for observing the northern hemisphere, but since its size is not large, the brightness will not be too high, it is estimated to be about 3, not far from the group of Taurus comet, the difficulty of observation is not yet small" . It is said that the middle of the end of December is a good time to observe the 46th comet. "About 9 am every evening, Taurus rises to the southeast, and the Pleiades group is very attractive. The interested astronomers can prepare a small telescope in advance and search for it near this magnificent cluster.The mysterious beauty of this comet with a tail.If atmospheric transparency is good enough, the possibility of detecting this comet with the naked eye is not excluded.
