The first of this year’s two “super moons” will appear Tuesday evening on the southeastern horizon when the moon rises at 9:21 p.m., assuming the sky is clear.
A so-called super moon occurs when a full moon coincides with its perigee (closest approach to the Earth) in its monthly orbit around the Earth. That makes it appear to be slightly larger than normal. Because of the moon’s elliptical orbit, there are monthly perigees and apogees (the furthest distance from Earth), and their distances vary through the year. Another super moon will occur on July 13.
The average distance from the moon to the Earth is 238,855 miles. On Tuesday, the moon will be 222,098 miles away, which will be its second-closest approach to the Earth in 2022. It will be even closer for the super moon of July 13, when it will be at its closest of the approach of the year, at 221,993 miles.
The moon will be farthest from the Earth — its greatest apogee of the year — on June 29, when it’s 252,637 miles away. You probably won’t notice, though, because it will be overhead during daylight hours.
One more astronomy note: The solstice that marks the official arrival of summer will occur June 21. On that day and the day after, Denver will have 14 hours, 59 minutes and 15 seconds of daylight. After that, the days will grow shorter until the winter solstice on Dec. 21.
