In 2153, Skalaar and Jonathan Archer landed on a class L planet with a cloudy atmosphere to escape Kago-Darr. The landing site appeared barren and cratered, but allowed them to get out and conduct repairs to the outer hull of Skalaar's shuttle without environmental suits. (ENT: "Bounty") Indri VIII was a class L planet that lacked animal life but used to be covered with deciduous plants until 2369. That year, the USS Enterprise-D had to witness a Klingon ship destroying the planet's lower atmosphere including all life with a plasma reaction. (TNG: "The Chase" )
