The moon is going to look huge tomorrow night (Dec. 3) because it's a supermoon.

And it will be the first and last time we will see a visually larger moon in 2017.

When to see it in Singapore

According to Moon Phases for Singapore, the supermoon will occur on Sunday, Dec. 3 at 11:46 pm.

Interested Singaporeans can try to catch a glimpse of it around that time.

What is a Supermoon?

A supermoon is popularly known as a full or new moon that coincides with the lunar orbit making an especially close approach to Earth.

It appears to be visually brighter and larger than normal to the naked eye.

The scientific term for supermoon is perigee syzygy.

Gurtina Besla, a professor at the Arizona University, explains:

"Perigee refers to the moon being at its closest distance to the Earth, and syzygy refers to the alignment of multiple bodies — the moon, Earth and sun need to be aligned for us to see a full moon.

So it translates to the closest separation between the moon and Earth when the Earth, moon and sun are aligned."

Next supermoon in 2018

If for some reason, you can't catch the moon in its full glory, you can always watch the live stream of the celestial event at the Virtual Telescope (3:45 am ET, or 16:45 pm local time on Dec. 4).

But if you're too busy for that, you can always wait till the next supermoon occurs on Jan. 2, 2018.

The last supermoon we saw was on Nov. 14 last year. It was the closest to Earth since 1948, making it the largest moon Earthlings saw in 70 years. The next time the moon appears this big will be in 2034.

Let's just hope we won't have cloudy skies.
