The brightest blue comet in the sky rushes towards Earth

The 46P / Wirtanen comet with green light will come close to the point that earth people can see clearly with the naked eye.

A small but extremely bright comet named 46P / Wirtanen is rushing closer to Earth, according to NASA. This is the comet of the "Jupiter" family , which is a group of 400 comets with orbits of 20 years or less with the farthest point from the Sun in orbit near Jupiter.

According to NASA calculations, the comet will approach Earth most closely with a distance of 11.586 million miles on 13 December 16 (GMT time, ie 20 hours on December 16, Vietnam time) , an extreme distance. close in astronomy. This will be the 20th access of comets since the 9th century AD.

You don't have to worry about watching it because this comet is extremely bright.The approach is very close, it will look as big as Jupiter and can be seen with the naked eye. If you have a professional astronomical observation device, it will be extremely brilliant.

46P / Wirtanen Comet was discovered in 1948 by astronomer Carl Wirtanen, at Lick Observatory (California - USA) and regularly visited the earth every 5.4 years. Since then, humans have never missed watching this beautiful green object, except for a visit in 1980, it is so close to the sun that it cannot be observed.

According to scientists, you can look at this comet as you look at the eastern horizon, after every sunset, for the whole month . However, if viewed with the naked eye, it will not be too bright. To clearly observe an object in the night sky, you need to choose a place with empty space and let your eyes familiarize with the darkness about 20 minutes before starting to observe.

During the time when this comet passed near the Earth, the tip of the comet could expand to about twice the size of the moon.
