4. When did Mars rush and when did Mars rise?

News from the website of China Journal: The nearest Mars to the Earth in 60,000 years has come! "I saw a particularly bright star in the sky due south tonight. Is that Mars? " "Then where can we see Mars?" These days, not only astronomy enthusiasts, but also ordinary citizens have shown great interest in Mars. Many readers called to tell us that they were all ready for this once-in-60,000-year opportunity.

Best time: In the early morning of August 27th, the reporter contacted Wang Sichao, a researcher at Nanjing Purple Mountain Observatory. Although the impact of Mars occurred in the early morning of 29th, the best observation time was the early morning of 27th. If you prepare a high-powered telescope, you may see all kinds of details on Mars in these two days.

Stargazing tip: The less light, the better. According to experts, Mars will appear in the southeast of the sky as soon as it gets dark, and will rise to the southeast of the zenith from 9: 00 pm to 10 pm, and reach the highest in the middle of the night. The elevation of Hangzhou is about 50 degrees. Then, it slowly descended to the west and disappeared before dawn (5: 10). Wang Sichao said that it is best to stay away from the city when watching Mars. Because there is generally less light pollution outside the city, less dust in the air, high visibility, and no buildings to block it, eyes can move with Mars without any obstacles. Of course, as a Hangzhou native, if you don't have time to go to the countryside, you can directly make an appointment with some friends, bring the corresponding equipment, and go to the open areas such as Baoshi Mountain before dark, waiting for Mars to rise.

Stargazing equipment: indispensable telescope Although the recent impact of Mars was the biggest in human history, no details on Mars could be seen by naked eyes. If you really want to see something on Mars, you must have some necessary equipment. Wang Sichao suggested that people who want to watch the impact of Mars should be equipped with a small telescope with a diameter greater than 10 cm and a multiple of 100 to 200 times. However, when watching Mars rush to the sun, because it lasts for a long time, the telescope is easy to get sour and shake when it is held in your hand for a long time, so it is best to equip it with a tripod. Of course, if you want to take a photo with Mars, which has been closest to the Earth for 60,000 years, you'd better prepare a digital camera or video camera.

Stargazing details: these things can be carefully examined. According to experts, you must look at these details when watching the stars: details 1: "Canal". The surface of Mars is covered with intricate mountains and canyons. When people observe with ground telescopes, they will see that the valley is shaped like an artificial canal. Detail 2: The polar cap, that is, the white covering of the polar regions of Mars. As early as17th century, astronomer Huygens discovered the polar cap. It is one of the most obvious signs of Mars. Its size changes with the seasons of Mars, expanding in winter and contracting in summer. Detail 3: Fire protection. Mars has two natural satellites-Phobos and Phobos. These two satellites are like two small satellites on Mars, with irregular shapes, like two potatoes bitten by mice. At that time, key observations can be made in the telescope. Detail 4: Sandstorm. On the day of "Dashong", the surface of Mars may be very fuzzy, and nothing can be seen clearly. It was a powerful sandstorm on Mars. The power of Martian dust storms is several times stronger than that of the earth, and it is common for dust storms to sweep across the whole of Mars. So if there is a big sandstorm, the surface will not be very clear. Humans have no way to deal with this kind of thing, and can only hope for the "weather" on Mars that day.
