Saturday Night Delight From 'Super Moon'
A so-called super moon is set to light up the sky overnight from Saturday into Sunday morning, bringing a lunar spectacle for amateur and professional astronomers alike.
Super moons happen when the satellite's closest approach to the Earth during its orbit - known as perigee - coincides with a full moon.
Saturday's "perigee moon", as it is known scientifically, will be as much as 14% bigger and 30% brighter than other full moons this year, says Nasa Science.
During this week's perigee, the moon will be 221,801 miles (356,955 km) from Earth.
That close approach will happen within minutes of the official full moon phase, which occurs at 4.35am BST on Sunday morning.
"Only one minute later, the moon will line up with Earth and the sun to become brilliantly full. The timing is almost perfect," Nasa said.
The super moon, a term coined in 1979, will also cause high and low tides to be slightly more extreme than usual.
But astronomers say there is nothing to fear - super moons are about picturesque moments and are not a threat to the planet.
"While we know that during new and full moons the tides are greatest - and if it's in concert with a storm surge it might produce unusual flooding - there is no scientific evidence that earthquakes and other natural disasters are connected," Geza Gyuk, an astronomer at the Adler Planetarium in Chicago, told National Geographic.
"Super moons have been happening for billions of years, and nothing particularly special occurs on these dates - except, of course, for a beautiful full moon."
The last super moon occurred in March last year, and was about 400km closer than Saturday's.
Sky News weather producer Chris England said most places in the UK will enjoy clear spells overnight - except southeast England and central Scotland, which will be cloudy.
