It’s not blue and it’s not really super!

There is a super blue moon tonight and tomorrow night. All that means is that there are 13 full moons in this twelve month period and this August there are two in the same month. This is the second and ‘blue’ moon. The moon also happens to be at its closest approach to the Earth, a few thousand miles closer, so it appears slightly bigger in the sky. The moons orbit is elliptical, so it has two centres of gravity and so sometimes it appears closer and sometimes further away. The next super blue moon will be in 2037. There are lots of articles on the Internet about it today.
