Is Mercury an irradiated ball of rock closest to the sun, not very interesting- Really? For example, if you lived on Mercury you’d have a birthday every 3 months because it completes one revolution around the sun in just 88 Earth days. Come and listen to Stephen Webber from Cardiff astronomical society, who will convince you that Mercury really is very interesting!

Er enghraifft, os oeddech yn byw ar Mercher byddech yn dathlu’ch pen-blwydd bob 3 mis gan ei fod yn cylchu’r haul un waith mewn 88 diwrnod daearol. Dewch i wrando ar Stephen Webber o Gymdeithas Astronomegol Caerdydd a fydd yn eich perswadio fod Mercher wir yn ddiddorol!

Event darkness

The Moon has a big impact on the visibility of celestial bodies in the night sky. Try to plan your stargazing when there is no bright Moon at night as this is when the skies will be at their darkest.

The below chart shows if and when the skies will be at their darkest during this event. Moonlight is shown in light yellow and the Sun's twilight in light blue. Midnight on the date shown is shown as a white line with sunset to the left and sunrise the next morning to the right. A black background with stars shows the best times for stargazing.
