The Harvest Moon signals the true start of autumn for astronomy fans.
It is the first full moon that takes place closest to the autumn equinox when the sun shines almost directly over the equator.
The name Harvest Moon comes from when farmers would use its bright light to extend the working day and gather in crops in preparation for winter, the Mirror reports.
It usually occurs before the equinox in September, but for us in the northern hemisphere, the Harvest Moon is rising late this year.
When is the Harvest Moon?
In 2017 the Harvest Moon will actually rise in October - it is taking place on Thursday (October 5).
This year's autumnal equinox was on September 22, which makes Thursday night's full moon the Harvest Moon because it is the closest full moon in the calendar.
October is usually reserved for the Hunter's moon but this year we're getting a late Harvest Moon.
The Hunter's Moon will rise on November 3.
When is the best time to see the Harvest Moon?
The 2017 Harvest Moon will be at its brightest at around 7.40pm on Thursday.
Harvest Moons can appear to look orange due to dust and clouds in the atmosphere, especially if you glimpse the moon as it is rising and close to the horizon.
But when it gets up into the centre of the sky, it will be shining bright white.
If the weather is clear stargazers will be able to see the Harvest Moon with or without a telescope, you'll just need to look up at the sky.
Is this year's Harvest Moon a supermoon as well?
No, while the Harvest Moon may appear slightly bigger because of its elliptical orbit around the Earth, it isn't considered a super moon.
Make sure you take a moment to appreciate autumn's most symbolic moon.
