Beta Mariotia III

Beta Mariotia III is a Class M planet located in the Beta Mariotia system, within a few days' travel of Starbase 44.

History
In 2266, a Harahni farming colony was established on the surface. Their intent was to reshape the world in the likeness of Harahn, so they transplanted a variety of plant and animal life from their homeworld including Harahni sheep, Harahni elephant-camels and teelak. Unfortunately, their plants had trouble growing in the native soil, and their animals were unable to eat the local plant life. Soil was modified in farming sectors over the next six months to compensate, but during that time many of their animals died. 

In 2267, about a year after their arrival, a large unidentified vessel assumed orbit around Beta Mariotia III and began barraging the colony with short half-life radiation. The barrage continued for two months. Responding to a distress call from the colony, the USS Enterprise (NCC-1701) arrived and engaged the vessel. 

The attacking vessel was found to be a 15,000-year-old automated T'Gai starship. The radiation barrage was stopped and the Harahni began adapting to use native resources instead of limiting themselves to what they brought with them.
