The last full moon of 2017 that will occur on December 3, 2017, will be a supermoon bringing a dramatic end to the year. A full moon happens at perigree – the time when the moon is closest to Earth and this time it will appear full for three days from Friday to Monday, making this a full Moon weekend. As the last full Moon of Autumn, this moon also has a special name and is known as the Frost Moon or the Moon Before Yule. It is also called Long Night Moon, or the Moon before Yule. In 1930’s the Maine Farmer’s Almanac first published Indian names for the full moons. According to this almanac, the Native American name given to this full moon was the Frost Moon as frosts appear at the end of the autumn or fall season. “Moon before Yule” was the name given by Europeans. Previous to this full moon Hunter’s Moon had occurred. Today’s full moon commemorates the Hindu festival of Dattatreya Jayanti.Also Read - Strawberry Moon 2021: When Can You See Last Full Moon of The Spring Season in India? Details Inside
This is the first of three supermoons as the full Moon occurs about 17 hours before perigree. The full moon will be a mere 492 km (306 miles) away from Earth, making it appear 13.6% larger in diameter and 29% larger in the area. The moon will also appear 7% more intense and brighter because the Earth will be at its closest to the Sun (called perihelion) in early January and due to this the Moon will get more sunlight to reflect. This is the reason winter-time supermoons appear brighter.
