This one is one of 4-6 super-moons a year on average. It doesn’t sound very special, but tonight's full moon lines up much more closely with perigee, which is the moon’s closest point to Earth.

This full moon falls only 22 minutes after the moon reaches perigee, the moon’s closest point to Earth for this month and year. At perigee, the moon lies only 356,991 kilometers (221,824 miles) away. Two weeks later, on July 7, the moon will swing out to apogee – its farthest point for the month and year – at 406,490 kilometers (252,581 miles) distant.

Full moons bring higher-than-usual tides, and perigee full moons bring the highest and lowest tides of all. Each month, on the day of the full moon, the moon, Earth and sun are aligned, with Earth in between. This line up creates wide-ranging tides, known as spring tides. High spring tides climb up especially high, and on the same day low tides plunge especially low.

Call it Rose Moon, Flower Moon, Strawberry Moon, Oak Moon, Cold Moon, or Long Night’s Moon. You choose your favorite name depending on your point of view from Southern, or Northern Hemispheres.
