What are the special astronomical phenomena of 20 18?

There are many astronomy enthusiasts around us; With the development of science, our understanding of astronomy has surpassed that of the earth. So do you know what special astronomical phenomena are there in 20 18? Let's take a look at it with the knowledge of the constellation.

Total lunar eclipse 20 18 There will be two total lunar eclipses around the world. Fortunately, the stage of total lunar eclipse can be seen twice in most parts of China. These two total solar eclipses occurred on June 365438+1October 3 1 day and July 28, respectively. The total lunar eclipse (red moon) lasted 1 hour, 16 minutes and 1 hour for 43 minutes respectively, which is worth looking forward to.

On July 27th, after a long wait of 28 months, Mars and the Earth finally met again on the same side of the sun. Seen from the earth, this red planet is opposite to the sun. It rises at sunset and doesn't set until sunrise. You can see it all night, and the brightness will exceed -2.7, which is dazzling.

Because the orbits of Mars and the earth around the sun are elliptical, the distance between Mars and the earth is different every time Mars rushes to the sun. In 20 18, Mars rushed to the sun, which was a particularly close encounter between Mars and the Earth. Recently, the distance between the two is less than 58 million kilometers, which can be described as Mars rushing. To the naked eye, Mars will be particularly bright, but in astronomical telescopes, Mars will be particularly huge, and even the polar cap and other geomorphological features of Mars can be vaguely seen.

A partial solar eclipse occurred on August 1 1, which was the only one that could be seen in China in 20 18. Except for parts of South China, most areas will see different degrees of partial solar eclipse in the evening, and the eastern region will also see the scene of falling with food.

The degree and time of solar eclipse are different in different areas. Generally speaking, the farther northwest the eclipse occurs, the earlier the eclipse occurs, and the greater the degree to which the sun is blocked when the eclipse reaches the northeast. Therefore, if you want to see the biggest total solar eclipse, it is a good choice near Jiamusi in the northeast, and you will definitely see the half-eaten sun fall below the horizon.

On August 13, the Perseid meteor shower was extremely strong. Perseid meteor shower has always been famous for its steady flow and numerous fireballs. According to IMO's forecast, the Perseid meteor shower in 20 18 will reach its maximum value from 4: 00 to 16 on August 13, Beijing time, with a peak flow of 1 10 per hour. The 20 18 rain in Yingxian coincides with the third day of the lunar calendar, and there will be no moonlight interference almost all night, so the observation conditions are very good. Although it is almost dawn in China when the maximum value comes, the discharge of Perseid meteor shower is considerable in the days around the maximum value, and the best observation time will be the late night of August in 12, that is, the early morning of August in 13.

12 14, the Gemini meteor shower is particularly large. Gemini meteor shower is one of the most stable meteor showers every year. According to IMO's forecast, Gemini rain in 20 18 will be a torrential rain at 20: 00 on February 14, with peak flow per hour 120. However, Gemini rain has performed well in recent years. In the past 20 17, the peak flow even reached about 150. Gemini meteor shower is characterized by a steady increase in flow before the maximum, and a rapid decline after the maximum, but occasionally super bright fireballs appear. The best observation time of Gemini meteor shower in 20 18 will be the night of 65438+February 14, that is, the day before the first quarter moon. There will be some moonlight interference in the first half of the night. After the moon goes down, you can wait for the fireball to appear in pure darkness.
