China News Service, Nanjing, March 17 (Yang Yanci) According to a news from the Purple Mountain Observatory of the Chinese Academy of Sciences on the 17th, a crescent moon will meet Mars and Aldebaran in Tianyu on the 19th, forming a piercing "red-eyed smiling face". ", staged the wonderful celestial phenomenon of "double stars with the moon".

  According to experts, Mars is the first planet outside the orbit of the earth and one of the four terrestrial planets in the solar system.

Mars has an orange-red appearance because the surface is covered by hematite (iron oxide).
