Astronomical science experts introduced that on the evening of September 16, the orange-red planet - Mars will "get close" to another orange-red star - Lisuwu , and a bulging moon will stage the "double red stars accompany the moon". At that time, as long as the weather is sunny, the public around my country who are interested can witness this wonderful scene with their naked eyes.
On March 26, 2021, the National Space Administration released two siding images of Mars in the southern and northern hemispheres taken by the "Tianwen-1" probe, , my country's first Mars exploration mission.

Mars is the first planet outside the orbit of the Earth . The surface soil is rich in iron oxide and appears orange-red. Because it looks like fire, its brightness changes and visual motion trajectory were very confusing to the ancients, so it was called "Yinghuo" in ancient my country.

According to modern astronomy, Hinasubu belongs to Taurus . As a bright star, Hisuwu often appears in ancient astronomical observation records in my country, and is the brightest star in Hisu in my country's 28 constellations system. Modern research shows that Hissuwu is a red giant that entered the late stage of star evolution. The hydrogen in its core has gradually dried up, mainly relying on helium fusion to shine and heat, and the overall appearance is bright orange-red.

Director of Tianjin Science Popularization Writers Association and Member of the Beijing Astronomical Society Liu Dongyu introduced that the "Double Red Stars Accompanying the Moon" this time is the lunar phase of the 21st of the lunar calendar; the brightness of Mars is about 0, which is closer to the moon; the brightness of Bisuwu is about 1, which is slightly darker than Mars and appears slightly farther below the moon. In the weather is sunny, if you fully develop your imagination, you can regard these three celestial bodies as a "smiling smiley face" hanging high in the sky.

Liu Dongyu reminded that these three celestial bodies rose late that night. The horizon height will not be more appropriate in the eastern part of my country until about 23:00; the western part will be later. Mars will always be in the Taurus region, which is more suitable for night observation. As a typical bright star in the winter starry sky, Hinasugu will also increasingly occupy the main position in the night sky. Therefore, starting from the evening of the 16th, it is also a good time for the public to get to know Mars and Hinasuo.
