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. The nearest human colony to Hitchemus was Chi Bootis.

Hitchemus was known for its arts and artists. (PROSE: 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. (PROSE: The Southwell Park Mermaid)

Bernice Summerfield visited Hitchemus when she bought a photograph of Aurigan artwork taken on Capella Four. (PROSE: Steal from the World)

Behind the scenes
Kate Orman's The Caterpillar Room, published in A Second Target for Tommy, features the Doctor, Fitz Kreiner, and Anji Kapoor returning to Hitchemus a century after the events of The Year of Intelligent Tigers. By this point, the humans and Hitchemus Tigers are in a truce while the rising oceans of the planet continue to threaten what little land remains.
