How you can see the biggest supermoon of 2022 tonight

For the second month in a row, stargazers will be treated to a supermoon when they glance up at the night sky.

July's "Buck" supermoon will be the biggest of the year, and should provide an even more spectacular sight than last month's "Strawberry" moon.

Here's how you can get a glimpse of it in Australia.

When will the Buck supermoon be visible in Australia?

This full moon has actually already reached its peak, doing so at 4.38am (AEST) on Thursday.

Fortunately, that doesn't mean you've lost your chance to see the supermoon.

NASA says the moon will appear full for "about three days", and Thursday night will still be an excellent sighting time – assuming the skies are clear of clouds in your area.

When will be the best time to see it?

Right after sunset is going to be the best time to view today's supermoon, although unlike some celestial events, there's a fairly broad window when you'll be able to see it – it won't be over in a few minutes.

"Unlike some astronomical events, there's not (a situation where) you've got to look at it this instant or else you miss it," Noah Petro, chief of NASA's Planetary Geology, Geophysics and Geochemistry Lab, said.

"There's really no moment that you have to be looking at it to maximise your enjoyment of the full moon."

For the clearest views of the moon, Petro recommended avoiding areas surrounded by tall buildings and thick forestry.

Why is it called the Buck supermoon?

This full moon is most commonly known as the buck moon because, in America, male deer, or bucks, fully grow out their antlers in July.

However, the full moon has been known by some other names.

In Europe, it is often called the hay moon for the haymaking season in June and July, while for Petro and other space enthusiasts, this moon is called the Apollo 11 moon.

Apollo 11 was the first mission to put humans on the lunar surface.

The mission launched on July 16, 1969, and landed on the moon on July 20, 1969.

What's the difference between a supermoon and a normal full moon?

While there isn't a single definition of "supermoon", the term typically refers to a full moon that can stand out more than others because it is within 90 per cent of its closest orbit to Earth.

This cosmic combo can – weather permitting – make the moon appear slightly bigger and brighter.

The Buck moon is the supermoon that will come closest to Earth this year, according to The Old Farmer's Almanac.
