Casperia Prime, or simply Casperia, was the inhabited prime planet of its star system. It was orbited by a large set of planetary rings.

In the mid-24th century, the Starfleet Bureau of Information billed this world as "The Vacation Capital of the Horvian Cluster." Its reputation as a resort was on par with Risa; among its sights were waterfalls. (DS9: "Change of Heart"; PIC: "Seventeen Seconds")

In 2374, Jadzia Dax planned her honeymoon with Worf to take place on Casperia Prime. (DS9: "Change of Heart")

Later that year, Dr. Julian Bashir planned to attend a medical conference on Casperia Prime before he was abducted by Luther Sloan, who wished to evaluate his potential as an agent, before recruiting him into Section 31. When discussing the trip with Bashir, Odo joked that doctors always held their medical conferences on sunny resorts. (DS9: "Inquisition")

In the early 2380s, Jean-Luc Picard and Beverly Crusher enjoyed shore leave together on Casperia Prime. However, Starfleet called Picard back early, which confirmed Crusher's belief that their relationship was ending; on that night, their son Jack Crusher was conceived. (PIC: "Seventeen Seconds").

According to Star Trek: Star Charts ("United Federation of Planets I"), in 2378, Casperia Prime was listed as a Federation member.


The SCE eBook entitled The Future Begins established Casperia Prime as being one of the Federation's most popular holiday destinations since around 2175, along with Risa, Wrigley's pleasure planet, and Phloston Paradise.

In the SCE eBook Ghost, Jennifer Almieri (β) and her husband honeymoon on Casperia Prime in 2327.

Starfleet officer Hawk's biography in the video game Star Trek: Starship Creator stated that he was severely wounded by a disruptor blast he sustained while shielding Federation Ambassador Louis Caggiano during an assassination attempt on Casperia Prime in the year 2369, for which he was awarded a Purple Heart. The game mistakenly spells the planet as "Kasperia".

The Pocket DS9 novel Hollow Men followed the events of "Inquisition", with Bashir reading through a number of papers that were presented at the conference he had missed.

In the Star Trek: Deep Space Nine - Mission Gamma novel This Gray Spirit, set in 2376, Thirishar ch'Thane (β) and Shathrissia zh'Cheen (β) vacation on the planet, where they spend several days rock climbing. Thirishar later said it was the best vacation she had ever had.

Casperia also appeared in the video game Star Trek Online in the year 2398, as the location of peace talks between the Klingon Empire and the Gorn Hegemony, mediated by the Federation. The talks were interrupted after an explosion, which was later determined to have been caused by a Klingon extremist group.
