For over half a century, Apollo asteroid 1566 Icarus held the record for the minor planet that passed closest to the Sun. From 16th-22nd June you can see this one-kilometre-wide space rock in backyard telescopes as it makes its closest pass to our planet until 2090.

Venus’ late night show in May

Even casual observers cannot fail to notice dazzling Venus currently gracing the western horizon at dusk. Owing to a favourable set of circumstances, the brightest planet is visible long after sunset. How late can you see it set in the British Isles? For those north of the Arctic Circle, Venus is presently circumpolar and doesn’t set at all!
