Mercury is the smallest and innermost planet in the Solar System. Its orbit around the Sun takes only 87.97 days, the shortest of all the planets in the Solar System. It is named after the Roman deity Mercury, the messenger of the gods.

Mercury will also reach it's highest point in the evening sky on the 12th Febuary. From Manchester, this apparition will be reasonably placed but nonetheless tricky to observe, reaching a peak altitude of 14° above the horizon at sunset on 13 Feb 2020

Constellation of the Month: Drago (shown 15th February 21:00)

Drago

Draco constellation lies in the northern sky. It is one of the largest constellations in the sky.

The constellation’s name means “the dragon” in Latin. Draco represents Ladon, the dragon that guarded the gardens of the Hesperides in Greek mythology.

Draco is one of the Greek constellations. It was first catalogued by the Greek astronomer Ptolemy in the 2nd century. It is a circumpolar constellation; it never sets below the horizon for many observers in the northern hemisphere.

Draco contains several famous deep sky objects, most notable ones being the Cat’s Eye Nebula (NGC 6543), the Spindle Galaxy (Messier 102, NGC 5866), and the Tadpole Galaxy.

The constellation Draco is associated with several myths, most frequently with the one about the 12 labours of Heracles, represented by the neighbouring constellation Hercules. In the myth, Draco represents Ladon, the dragon that guarded the golden apples in the gardens of the Hesperides.
