How to best see the supermoon

Tonight, the moon will reach "perigee", its closest point to earth, meaning it will be a lot more noticeable than usual.

Space expert Professor Heather Couper told the Today programme that if it is a clear night, the moon will look about 30 per cent brighter and bigger than usual, but the gravitational effect is "not much bigger".

Prof Couper added that if you want to view the moon at its normal size, you should stand with your back to it, lean over and and view it from between your legs, which will put it better in proportion.

First broadcast on the Today programme on Saturday 22 June.
