The History" (hoax) is as follows: If you look in the night sky today, August 27, you will see Mars appear as large as moon; Unfortunately, you won't see it. This dumb hoax occurs almost every year, with the promise that no one has seen the phenomenon to date and that it won't happen again for hundreds of years. It is also known as the farce of the two moons.
It is obvious that the exciting "news" is a lie and of course does not answer the question why Mars will suddenly look exactly the same as the moon?
But as we have seen several times, even the most obvious lie can be spread very easily by social networks, or by websites that they collect clicks offering garbage. So before it starts to spread and go viral it would be good to know about it.
Just ignore it if you see it in Facebook Your feeds today.
