The moon of the third day of the first month. China Broadcasting Network Beijing, August 20 News According to the Voice of China's "CCTV News" reported at 15:08, in recent days, there is news that on August 27, that is, at 0:30 a.m. next Friday, Mars is about 55 million kilometers away from the earth, and Mars will be as big as a full moon with the naked eye, and the sky will present an astronomical spectacle of two moons. Rumor has it that this celestial phenomenon is very rare, and the next time it happens is in 2287, so it can only be seen once in a lifetime.

This rumor has been frequently used on Weibo and forums. In response to this rumor, Zhu Jin, director of the Beijing Planetarium, refuted the rumor that this is absolutely impossible! Immediately connect with Zhu Jin to listen to his explanation.

Moderator: When you say that the rumors of this celestial phenomenon are impossible, do you mean that it could not happen on August 27 this year? Or is it possible that even if there is a so-called full moon on Mars, there will be no two moons?

Reporter: On August 27 this year, Mars was 320 million kilometers away from the Earth, about 4 small seconds in size, which is 1,450 times the size of the Moon. This will not be the case when Mars is at its maximum, and the best time is 1 75 of the Moon.

It is only a bright spot to the naked eye, and it will only make a difference in astronomical telescopes.

Moderator: Will there be any special celestial phenomena on August 27 this year? Why are there rumors of two moons?

Reporter: There are no special celestial phenomena per se. On August 27, 2003, Mars opposition, which was 55 million kilometers from the Earth, reached about 1,75 of the Moon, and by the year 2287, it was a very close distance.

Every time the Earth makes more than one revolution, it will be closer to Mars again. The principle of the "Martian opposition" is similar to that of the Full Moon, and its illuminated side of the Sun is facing us on Earth.
