Hitchemus

Hitchemus was a planet which orbited Beta Canum Venaticorum (also known as Chara), a G-type star. A day lasted for twenty-two hours with no more than six hours of darkness. There was only one landmass on the planet (Port Any), as Hitchemus was seven eighths ocean.

Hitchemus was known for its arts and artists. (EDA: The Year of Intelligent Tigers)

The Doctor once saw Horseshoe Crabs deep in an ocean trench on Hitchemus, living in the remnants of a human city. (ST: The Southwell Park Mermaid)
