"A supermoon may sound exciting, but it’s a modest coincidence.
As the Moon orbits Earth, its distance from us varies from 357,000 to 407,000
kilometres. When the Moon and the Sun are in almost opposite directions from
Earth, we get a full moon. A “supermoon” is a full moon where its position
along its orbit is within 10% of its closest approach to Earth. That’s it.
This means a supermoon has an apparent diameter that’s 14% larger than the
smallest possible full moon. That’s not a lot. You can’t really notice the
difference by eye.
As an astronomer, I have a problem with supermoons. There are genuine wonders
to see in the night sky, so don’t be disappointed by a dull, overhyped
supermoon."
