Mimban, formally known as Circarpous V, was the home planet of the Coway, the Mimbanites, and the extinct Thrella. Although originally named Circarpous V, the planet was never colonized by the Circarpousians. The planet, locally known as Mimban, was in the Circarpous system.
Mimban is a cloud-covered jungle world that was largely unexplored. The atmosphere over Mimban was very turbulent. Starships without special hulls faced tremendous danger from the energy storms that streaked the stratosphere. The surface of the planet was damp, and the perpetual mist made it difficult to distinguish night from day.

In SOLO – A Star Wars Story we find a reluctant Han fighting on the side of the Empire to bring order to the hostile indigenous people. Here is were Han also crosses paths with Beckett (played by Woody Harrelson), Val (played by Thandie Newton) and Rio (voiced by Jon Favreau).
With Han stepping out of line, not for the first time, he is thrown into a pit for “The Beast” to eat him…..but luckily for Han he can speak a little Kashyyykian taking out a few Mudtroopeers for good measure.
The scenes for Mimban were all filmed tbc…
The planet’s history stretches even further back than the novel Splinter of the Mind’s Eye, too. Mimban was first conceived by Lucas as “the Bog Planet” in his earliest Star Wars scripts. While the Bog Planet was cut out of the 1977 film, Lucas later returned to the idea in The Empire Strikes Back with Dagobah. For a planet most casual fans of Star Wars have probably never heard of, Mimban carries quite a bit of behind the scenes history with it.
