A solar eclipse takes place when the moon crosses between the sun and Earth, which blocks out a portion of the sun’s rays, according to NASA. This eclipse is an annular one, meaning the moon is far enough away from the Earth that it appears smaller than the sun. When the moon crosses path with the sun, it will appear smaller than the fiery star, leaving room for a bright light to glow around the edges – dubbed a ‘ring of fire’.
The ‘ring of fire’ will be visible to some people in Greenland, northern Russia and Canada, according to NASA.
Other countries in the Northern Hemisphere, including the UK and Ireland, will be able to see a partial eclipse where the moon only covers a fraction of the sun.
A fingernail-shaped shadow will cover a different percentage of the sun, depending on where it is you live.
The path of annularity, which traces where the ring of fire is visible, will begin over the northern US, then cross over the Arctic before finishing up in northeastern Russia, reports the Farmers’ Almanac.

The Royal Museums Greenwich in south London is also hosting a live stream, for the Royal Observatory, which is the traditionally situated location of the prime meridian.
The live stream will begin at 10.05am BST on both Facebook and YouTube.
The Royal Observatory said in a statement: “Our expert astronomy team will help explain the science of solar eclipses and answer all your space questions.
“You will see exactly the same view as our astronomers, with a live telescope feed of the sun from our state-of-the-art Annie Maunder Astrographic Telescope.”
