Star Trek: Discovery has ventured to some of the franchise's finest planets across its four seasons. As the first streaming show to debut on CBS All Access in 2017, Discovery paved the way for the modern era of Star Trek. Following the exploits of Michael Burnham and the USS Discovery crew, the series chronicles their adventures in the 23rd and 32nd centuries after a 900-year leap into the future. Discovery played a pivotal role in revitalizing the Star Trek franchise, which had been dormant for 12 years, and inspired the creation of other recent series by rekindling interest in the iconic universe.
While Star Trek: Discovery boasts a distinct tone and style that sets it apart from the "classic" Star Trek, the series skillfully incorporates many beloved elements that define the franchise. One such way is by showcasing the USS Discovery's visits to captivating planets. Despite never being assigned a five-year mission like the USS Enterprise, the Discovery dutifully embodies the mission's directive to "explore strange new worlds." In fact, even within its relatively short time on streaming, Discovery has introduced the franchise to a plethora of captivating new planets.
10 Ni’Var
9 Boreth
Ni'Var, formerly known as Vulcan, has undergone a significant transformation in the Star Trek universe. Originally introduced in Star Trek: The Original Series, the planet has now evolved into a new world in the 32nd century as depicted in Star Trek: Discovery. As a result of the Romulan Supernova, the Vulcans decided to accept Romulan refugees onto their planet, leading to a merging of cultures and a subsequent renaming of the planet. While the physical aspects of Ni'Var remained unchanged, the profound changes in its society and culture make it feel like an entirely different world, particularly for the crew of Discovery and especially for Michael.
Boreth's significance was further expanded upon when Star Trek: Discovery introduced it in season 2. The show delved deeper into the planet's history, specifically focusing on the Klingon monastery situated on Boreth. This monastery held great religious importance for the Klingons, making Boreth a revered holy site. Captain Christopher Pike (Anson Mount) found himself drawn to the planet due to its connection to his future life-altering accident. During his visit, he sought a time stone from the monastery. Prior to this, Boreth had been explored through the experiences of Worf (Michael Dorn) in both Star Trek: The Next Generation and Star Trek: Deep Space Nine.
8 Pahvo
Pahvo, an intriguing planet showcased in Star Trek: Discovery season 1, served a crucial purpose in aiding Starfleet's advantage in the ongoing Klingon War. This celestial body possessed a fascinating attribute—a naturally emitted frequency that resonated through every living organism, including the indigenous Pahvans. Living in perfect harmony with their home, the Pahvans were renowned for their pacifist nature and valiantly attempted to mediate the brutal conflict between the Federation and the Klingons, albeit with perilous consequences. While Pahvo may not have ranked as the most captivating planet ever explored by the USS Discovery, its awe-inspiring visuals, particularly the majestic crystal tower that broadcasted the planet's harmonious frequency into the vastness of space, left a lasting impression.
7 Species 10-C’s Planet
Species 10-C remained a perplexing enigma throughout the entirety of Star Trek: Discovery season 4. Nevertheless, the anticipation surrounding their planet was well justified, as it proved to be a fascinating revelation. Situated beyond the confinements of the Galactic Barrier, this celestial body had once been a colossal gas giant. However, an unrelenting meteor shower ravaged its atmosphere, gradually dissipating the layers of gases and leaving behind an arid desert. Remnants of the deceased 10-C creatures, alongside the remnants of the elaborate nurseries built by their species for their offspring, were the sole vestiges that endured. Combining the planet's extraordinary location with its profoundly otherworldly inhabitants, the allure of Species 10-C's homeworld proved to be highly captivating during Discovery's explorations, though not without leaving a lasting impression.
6 Su’Kal’s Dilithium Planet
5 Kwejian
The dilithium planet, known as Su'Kal's planet, played a significant role in the main plot of Star Trek: Discovery season 3. Situated within the Verubian nebula, this planetoid was constantly bombarded by intense radiation due to its high concentration of dilithium. Unbeknownst to the crew for much of the season, it served as both the problem and solution to their mission. Su'Kal, who possessed a unique psychic connection with the planet, inadvertently triggered the devastating event known as the Burn when he witnessed his mother's death. Although the planet took center stage in the storyline of Discovery season 3, its true fascination lies in its profound bond with Su'Kal.
Renowned for its breathtaking beauty, Kwejian made its debut in Star Trek: Discovery season 3 before taking on a pivotal role in season 4. Despite being introduced midway through the series, Kwejian's natural allure and being the cherished abode of Cleveland Booker (David Ajala) immediately bestowed it with significance for the crew of Discovery following their leap to the 32nd century. Tragically, Kwejian's importance escalated further when it fell victim to complete annihilation by the DMA in Discovery season 4 – an event that catalyzed the overarching narrative of the season and profoundly impacted Book's personal journey.
4 Terralysium
Although not the most visually or geographically captivating planet, Terralysium stands out due to its population. Rescued by Gabrielle Burnham, known as the Red Angel, during Earth's World War III, a group of humans were transported to the planet and established a colony named New Eden. Located in the Beta Quadrant, Terralysium lay far enough from Earth for its inhabitants to evolve separately from the rest of humanity. This unique scenario provided Star Trek: Discovery with one of the most intriguing science fiction concepts explored in season 2 when the crew visited Terralysium in search of the Red Angel.
3 Kaminar
Star Trek: Discovery showcased the visually captivating planet of Kaminar, intertwining it with a compelling narrative centered around one of the main characters. Serving as the homeland of Saru (Doug Jones), Kaminar assumed significant importance in season 2 as it became the destination of the enigmatic Red Angel. In episode 6 of season 2, titled "The Sound of Thunder," Discovery delved into the intricate dynamics between the planet's two indigenous species, the Kelpians and the Ba'ul. Even after the temporal leap, Kaminar remained intricately tied to Saru, with his storylines seamlessly connected to the planet. Apart from its role in the Kelpian and Ba'ul conflict, Kaminar's distinctive natural beauty solidified its position as one of Discovery's most memorable and awe-inspiring locations.
2 The Mycelial Network
1 The Mirror Universe
Although not officially recognized as a planet, nothing is more closely associated with Star Trek: Discovery than the captivating Mycelial Network. This intricate network served as the power source for the USS Discovery's spore drive, a concept completely unique to the show and a defining characteristic that sets it apart from the rest of the franchise. What truly sets the Mycelial Network apart is its expansive presence across Star Trek's multiverse, with Discovery delving deeper into this exploration than any other installment in the series. Within the network, an array of species, including mycelium, reside, transforming it into a captivating "strange new world."
The Mirror Universe in Star Trek: Discovery stands out among all other explored planets due to its reimagined portrayal. While the concept of the Mirror Universe was first introduced in Star Trek: The Original Series and featured in some episodes of the 1990s-era Star Trek shows, Discovery season 1 significantly enriches its lore and backstory. Notably, Emperor Phillipa Georgiou (Michelle Yeoh), a standout character in Star Trek: Discovery, hails from the Mirror Universe, further solidifying it as one of the most intriguing and unique worlds in the series.
