This will be the second total solar eclipse of 2018, after the one that took place on January 31st. On this occasion, it was a "supermoon" because the satellite looked to be particularly big.
On Friday, on the other hand, will be a "miniluna" because it will be almost at the farthest point of Earth and it will give the sensation of having a smaller size. Also for this it will take longer to cross the cone of the shadow.
Deprived of the sun's rays, the moon will darken and become red. This color is explained by the fact that the Earth's atmosphere diverts the red rays from the sun into the shadow cone, and the Moon can reflect them .
Depending on atmospheric conditions and, in particular, pollution, the moon can acquire a very dark reddish gray, or color a more intense red if there are no particles in it. ;atmosphere.
