As we said above, the year 2017 will have four supermoons: the new moons of April, May and June, and the full moon of December.
The new moon on May 25 presents the closest supermoon of the year (357,265 kilometers or 221,994 miles). This is the first time since the year 2009 that the closest supermoon is a new moon (instead of a full moon) and the first time since 2009 that the closest supermoon is more than 357,000 km distant.
Farthest full moon of 2017 on June 9. One fortnight (approximately two weeks) after the year’s nearest new moon on May 25, it’ll be the year’s farthest and smallest full moon on June 9, 2017. People are calling this sort of moon a micro-moon.
Bottom line: The first supermoon of 2017 comes when the moon turns new on April 26, 2017! No, you won’t see this moon, because the new moon hides in the glare of the sun, but you might discern the higher-than-usual tides along the ocean shorelines.
