Sky Matters: Supermoon, second moons, and Comet C/2023 A3

"While we’re used to Earth having one Moon, it will actually have two (kinda) during October and November."

People gather as the supermoon rises over St Michael's Tower, atop Glastonbury Tor, which occurs when the moon appears 30% brighter and 14% bigger in the sky. Picture date: Wednesday September 18, 2024. PA Photo. Photo credit should read: Ben Birchall/PA Wire

Another month. Another supermoon. On October 17. We could almost be forgiven for taking the phenomenon for granted.

The Moon orbits the Earth in a slightly oval movement, so sometimes the Moon is closer to the Earth and sometimes it’s farther away.
