==Suliban gas giant ==
In 2151, Enterprise encountered a class 7 gas giant while following the warp trail of a Suliban vessel. Under the cyclohexane layer of the planet's atmosphere was an unexpected layer of liquid phosphorus. The planet could be observed to have at least one moon.
A Suliban helix composed of many s was located in the planet's atmosphere, just beneath the liquid phosphorus layer. Enterprise Captain Jonathan Archer boarded the helix and used a device to separate the cell ships from the helix. ()

==Suliban hiding planet ==
Orbiting one of the stars in a binary system 2.5 light-years from Paraagan II, this planet had two moons. In 2152, a Suliban stealth cruiser hid on this planet's inner moon. ()
==Symbiotic lifeform homeworld ==
The planet had a moon or a large neighboring planet. Its surface conditions didn't allow Humans, Vulcans or Denobulans to set foot on it without wearing an EV suit.
In early 2152, after Enterprise had been infected with a symbiotic lifeform, they were able to find the location of its homeworld with the help of the Kreetassans.
Upon finding the planet, an away team went down to return the lifeform, and its severed tendril that Phlox examined, to the larger creature that took up much of the planet. ()
==System J-25 planets==
At least six planets were part of System J-25. One M-class planet was uninhabited and was located seven thousand light years from 24th century Federation space.
Prior to the mid-2360s, the sixth planet was home to a highly industrialized civilization with cities linked by a system of roads. When the Borg attacked, the attacking ships removed cities, which caused rips to appear on the planet’s surface. In 2365, the Federation starship scanned this planet, noting that the rips were very similar to the scarring detected on several Federation and Romulan outposts along the Romulan Neutral Zone in 2364, which had removed all machine elements on the planet.

==System with shifted orbits==
This system contained at least three planets. One of them was detected to have undergone an orbital shift by Starfleet, taking it between two gas giants. The gas giants' influence was expected to superheat the core of this planet, covering the planet with erupting volcanos in no time. Enterprise was ordered by Admiral Forrest to study it. While the planet initially appeared lifeless, the seismic activity unearthed subterranean microbes. ()
==Takara sector planet==
An ice-covered class L world was located in the Takara sector, just outside the Alpha Quadrant.
In an alternate timeline, this planet was the crash site of following a disastrous use of the quantum slipstream drive. ()
==Terra Nova system planets==
This system, located less than twenty light years from Earth, contained Terra Nova and two other planets. ()
==Terran base==
This planet was located in the Badlands.
In the mirror universe, this planet hosted a base used by the Terran Rebellion in 2371. ()
==Tessic's species homeworld==
The homeworld of Tessic's species was a planet far away from the planet on which some members established a mining colony. ()
==Tkon Empire throne world==
This inhabited planet, the throne world of the Tkon Empire, orbited a blue giant star in sector 9. 
600,000 years ago, the planet's sun went supernova, resulting in the destruction of the planet and the deaths of billions. ()
==Trellium mining planet ==
The trellium mining planet was located about a six-week journey inside the Delphic Expanse. Trellium-D was mined there. The atmosphere of the planet was extremely polluted; many of the staff wore breathing masks and sustained survival on the surface was impossible. Members of thirty-one different species worked in the mines in some capacity.
Enterprise visited this planet in September 2153 because a freighter captain informed them that he had taken a Xindi there some time ago. Upon arrival, Captain Jonathan Archer and Commander Tucker were forced to provide a half-liter of liquefied platinum to the foreman of the north mine to see the Xindi, a Primate named Kessick.
It turned out to be a trap, however. The miners worked by capturing ships and forcing their crew to work as slaves. Enterprise was barely able to escape, but Kessick died in the attempt. ()
==Uninhabited planet==
 had been exploring this planet for three days in March 2153 when they were forced to recall their three surface science teams to pursue a bounty hunter who had captured their captain. They had also put down a number of crewmen on it for shore leave.
Among the planet's most enjoyable regions were equatorial range, including a north summit with an inspiring view. In the north there was the Rykos shoreline, the southern tip of which was 227 kilometers from the polar island chain. These islands featured a pyroclastic debris field, lava tubes, and the hydrothermal pools of Ren-gham. The planet also featured ravines. However, as Skalaar mentioned these things after learning Archer's name, it is possible he made these features up to earn Archer's trust and be able to kidnap him.
The planet supported life, for example a species of marsupials whose saliva was a natural anti-coagulant. There was also an unusual microbe which was capable of inducing pon farr in Vulcans. The microbe was also suspected of being more dangerous to Humans than to Vulcans or Denobulans. ()
==Vintaak system gas giant ==
The Vintaak system contained at least one planet, this ringed gas giant with several moons. In the mirror universe, it was located in Tholian space, and one moon contained a Tholian base. ()
==Volterra Nebula planets==
Two unnamed gas giants were located in the Volterra Nebula, a stellar nursery. In 2369, the visited this nebula for a three-week analysis. ()
==Vulcan monastery planet ==
This planet, between the neighboring Vulcan and Andorian systems, was the site of the monastery at P'Jem. The planet was the site of the first contact between Andorians and Humans.
A nearby ringed moon was visible in the sky of the planet. The surface featured several mountains, many trees and several other plants, canyons and a foggy air. There was also at least one lifeform native to the planet.
The planet was known to the Vulcans since at least the early 1st millennium BC. The construction of the monastery at P'Jem, later consecrated to the memory and teachings of Surak, predated the Time of Awakening by over twelve centuries.
By the 22nd century, the Vulcan High Command thought to capitalize on the planet's proximity to the Andorian system by installing a secret long range sensor array there. The ancient monastery provided cover for this listening post.
Certain Andorian factions remained suspicious even after the peace treaty with the Vulcans. Andorian Imperial Guard commandos forcibly searched P'Jem twice before the successful June 2151 raid led by Thy'lek Shran. ()
Within a year, the spy station and its ancient cover had been destroyed. ()

==Xindi-Arboreal colony planet ==
This inhabited planet, located in a system within the Delphic Expanse, was the home to a Xindi-Arboreal colony. It was located near Tarquin's planet and had one moon. It was home to the indigenous tree scarab and contained several deposits of topaline ore. 
During the mid-22nd century this planet was home to a Xindi kemocite refining facility, at the time the planet had no artificial satellites or orbiting starships. 
In October 2153, Captain Jonathan Archer of the Earth ship came to the planet, on a tip from Tarquin while searching for the Xindi weapon. ()
== Xindi Council planet ==
The Xindi Council planet was the home to the Xindi Council. Its location was top-secret, and the planet was located inside a security zone. The planet was located approximately fifty light years from the Sol system.
The Council chambers were located in a fortress built into a mountainside by the Xindi-Avians sometime in the 2nd millennium BC. The fortress was two kilometers above ground level and was perfectly concealed by the cloud layer that surrounded it. The only way in was through the air.
After the Xindi weapon's location on Azati Prime was discovered by the Humans, it was moved to the Council planet. It was located in a large underground facility in a rocky portion of the planet. ()
