The Megara Galaxy, (Numerically designated KK 77) is a Sb-class spiral galaxy located close to the Lewis Galaxy in an area called Herschel Space. It is one of the first galaxies in which settlers from the Lewis Nations arrived in as well. The Megara Galaxy is often referred to as the 'Galaxy of Silk' from its very soft and light appearance.

The Megara Galaxy is located very close to the Lewis Galaxy, and not too far away from the Elcano Galaxy. It was the first galaxy to be colonized by humans in the Lewis Galaxy with it's first colony, Turon.
