Nemo 3a, nicknamed the "Space Whale" by locals, is the moon of Ergo (Nemo III). A captured asteroid, it is oblong in shape with one end tapering into a smaller one. The silhouette is said to resemble a whale, an ocean mammal indigenous to the planet Earth (Sol III) but not found on Ergo. Local businesses have built a tourist industry around the moon, and sell souvenirs ranging from novelty t-shirts to replicas of the Space Whale.
