The third full moon of the year will be visible tonight (March 7), reaching its peak at 12.40am in the UK.
Known as a Worm Moon, it occurs during the changing of the seasons from winter to spring. The full moon is the lunar phase when the moon appears fully illuminated from Earth's perspective.
They occur every 29.5 days, which is the time it takes for the Moon to orbit the Earth and complete one lunar phase cycle. There will be 13 full moons this year, with two falling in August. But why is tonight's full moon named a Worm Moon?
