The Only Supermoon of 2017 Is Happening. Here's When to View It

December's supermoon can best be seen Saturday night.

According to a press release issued by Poornaprajna Amateur Astronomers' Club Co-ordinator Dr A P Bhat, supermoons happen when a full moon approximately coincides with a moon's perigee or a point in its elliptical orbit at which it is closest to earth.

THE last full moon of this year, on Sunday, December 3, will be a supermoon - a phenomenon that occurs when the moon is closest to the earth, which makes Earth's natural satellite appear bigger and brighter. That kind of full moon won't be seen again from Earth until 2034, according to NASA.

There has been other reported times this year where the moon has been closer to Earth, however it wasn't considered a Supermoon because it didn't land on a day where it was a full moon.

The difference is noticeable for close observers - particularly if the moon is near the horizon, where it can be compared with terrestrial landmarks.

If you aren't able to observe this weekend's supermoon, don't worry: The new year kicks off with two supermoons straight from the gate. Supermoons are set to occur twice in January, on the 2nd and 31st. Its distance from Earth would be 3,57,983 km.

The Slooh Supermoon Challenge livestream will kick off on Sunday December 3 at 9pm EST (Monday December 4 at 2am).

If you're unable to see the supermoon, you won't have to wait long for another opportunity.

Just to be clear, the supermoon is only the moon-there will be no eclipse and no colors. One is offered by the Virtual Telescope Project based in Rome. In fact, the supermoon slated for January 31, 2018, will be both, making it a Super Blue Moon.
