The last full moon of 2017 will be the first, last and only supermoon of the year that can be seen with the naked eye.

A supermoon occurs when the full moon is at its closest distance to earth, a point which is called the perigree.

Supermoons can appear up to 14 per cent larger and 30 per cent brighter than a full moon at its furthest distance from earth.

This December's supermoon made its appearance Sunday at 11.57pm.

However, this supermoon kicks off a "trilogy" of supermoon appearances, the next ones calculated to emerge on Jan 1 and 31, 2018.

Experts say the supermoon on Jan 31 would be a special one, as it would feature both a lunar eclipse and a blue moon (the second full moon in a month).
