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!
