As shooting-star devotees prepare for the naked-eye spectacle of the Geminid meteor shower in mid-December, owners of small telescopes can also witness the close passage of the meteors’ parent body — a curious “rock comet” known as 3200 Phaethon, galloping through the constellations of Auriga, Perseus, Andromeda, Pisces and Pegasus at a rate of up to 15 degrees/day.
