Vulpecula the Fox, Delphinus the Dolphin and Sagitta the Arrow are located in and around the Summer Triangle. These are some of the smallest constellations in the night sky.

The Summer Triangle consists of three bright stars – Vega, Deneb and Altair – in three separate constellations. If you can find the Summer Triangle, you can use it to locate three of the sky’s smallest constellations: Vulpecula the Fox, Delphinus the Dolphin and Sagitta the Arrow.

All three would be impossible to see from the city. And personally – true confession ahead here – I’ve never managed to identify Vulpecula in my 30+ years of stargazing. It’s just so faint and so small!

On the other hand, the little constellations Delphinus and Sagitta are very distinctive. They’re easy to see in a dark country sky, because both actually look somewhat like the objects/creatures for which they’re named. Delphinus is supposed to be the Dolphin that carried a Greek poet – Arion – safely away from his enemies. Sagitta is sometimes considered to be an arrow shot from the bow of Hercules.
