Rare Blue Micromoon Rises This Weekend — Here's How to See It
On Sunday, May 31, a rare Blue Moon and micromoon will peak, combining the second full moon of the calendar month with the Moon's farthest point from Earth.
The phenomenon occurs because the lunar month and calendar month are slightly out of sync, while micromoon status results from the Moon being near apogee, its farthest orbital point.
At 406,135 kilometers away, this is the smallest full Moon this year, appearing about 6% smaller than average, according to Laura Driessen of the Sydney Institute.
For observers in Argentina, Chile, New Zealand, and Australia, the Moon will temporarily obscure Antares, a red supergiant star 550 light-years away in the constellation Scorpius.
Such a concatenation of circumstances will not recur until 2053, offering skywatchers a rare opportunity to witness the combination of two distinct astronomical phenomena simultaneously.
