At 22:18 on October 6 this year, Mars will travel to the closest point to earth. Astronomical experts said that under fine weather conditions, the Chinese public can enjoy the super bright Mars, whose brightness even surpasses that of Jupiter that night, becoming the “brightest star” in the night sky. Mars appears as a bright red object in the night sky. Because Mars is similar to earth in many aspects, and its volume is only about one seventh of that of earth, it is also called “pocket earth”. According to Shi Zhicheng, member of the Chinese Astronomical Society and director of the Tianjin astronomical society, Mars “collided with the sun” on October 14 this year. Since the perihelion of Mars and the earth are not on the same equatorial line, the day of “sun striking” is often not the closest time between Mars and earth. Usually, they are closest, and may be a few days ahead or a few days later than the “chongri” date. This time, Mars is closest to earth, eight days ahead of the date of the sun’s impact. < p > < p > the closest period between Mars and the earth is about 2 years and 2 months. Due to the large eccentricity of Mars, the distance from the earth varies greatly every time. The nearest time is within 60 million km, and the farthest time is more than 100 million km. This time, Mars’s nearest earth occurred at 22:18 on October 6, more than 62 million kilometers away from earth. < p > < p > Mars is in a “retrograde” state when it is closest to the earth and “thrusts into the sun”. During the retrograde period, the brightness of Mars gradually increases, which is very suitable for observation. < / P > < p > watching the bright Mars is not limited to the night of the 6th, but the whole October is a good time to observe. “As long as the weather is fine, after dark, if you look up to the eastern sky, you will see the bright red and shining Mars.” Shi Zhicheng suggested.
