Planets were, simply speaking, large spherical masses in space.
There are a number of highly unusual planets in the universe, including Magla, in reality an immense amoeba with a crust-like shell (DW: Destiny of the Daleks), and the artificial planet Arcadia. (NA: Deceit)
Some planets were artificially accelerated through the interference (intentional or not) of other life forms. Normally in these cases large starships provided the initial large mass which began the process of planetary formation. Such a fate befell the Minyan ship the P7E by accident (and nearly also happened to another Minyan vessel, the R1C) (DW: Underworld), and the vessel carrying the last of the Racnoss by design. (DW: The Runaway Bride)
A planet is a celestial body typically found in orbit around a star. Planets are typically sphereoid and may have other bodies in orbit of themselves such as moons, rings or artifical satalites which can include communications or defence technology or orbital facilites such as starbases and shipyards. There are two basic types of planets, small solid rocky planets which may have a thin atmosphere and gas giants which are almost entirely atmosphere. Small planet like bodies are planetoids or dwarf planets and smaller bodies still are asteroids.
The Federation classified planets it cataloged based on criteria such as atmospheric composition, surface temperature and conditions, the size of the body and the presence of animal and plant life. This system is used to determine the suitability of the planet for exploration, colonization and scientific research.
Each class of planet is assigned a letter in the alphabet based on its suitability. For example, Class M (sharing meaning with the Vulcan designation Minshara class) is applied to planets that can support life without any special circumstances, such as Earth, Vulcan or Cardassia.

Planets are large spherical bodies of matter that are in orbit around a star. Along with those of the Sol system, many planets in other star systems are known to exist. Some of Earth's most ardent champions (and deadliest enemies) originally hailed from other planets.
Below is a list of known planets and some of their history as it relates to the heroes of our planet.

A planet is a celestial body of a certain shape and size with certain characteristics. Some of these characteristics include gravity creating a sphere-like shape and being small enough to be unable to create thermonuclear fusion. Most planets, but not all, orbit one or more stars.
A planet usually has a diameter above 100 kilometers; celestial bodies below this size are usually classified as planetoids or asteroids. Their surfaces, compositions and masses can vary from planet to planet. For example, some planet surfaces may be completely or mostly comprised of water, while other planet surfaces are completely gaseous.
A planet was a celestial body that was in orbit around a star, was neither a star nor a moon, and had cleared out the area around its orbit as it formed by causing all other smaller bodies in its orbit to accrete with it. As a consequence, it would not share its orbital region with any other bodies of significant size, except for moons or those collected later under its gravitational influence.
Depending on the tilt of the planet's axis, planets also had varied seasons with ranging temperatures and weather. Planets were extremely varied in terms of environmental conditions and landscape, ranging from completely oceanic (such as Manaan and Kamino) to thick arboreal rainforests (such as Kashyyyk and Felucia). Some planets, such as Hoth, were completely frozen, while other planets, such as Nelvaan, were experiencing an ice age. Some planets, like Geonosis, Korriban, and Tatooine, were completely barren and desolate, covered in little more than rock and sand; while others (such as Coruscant and Taris) became an ecumenopolis, in which the entire planetary surface was covered by one gigantic city. Many planets, like Dantooine, Naboo, Alderaan, and Corellia, contained a mix of landscapes, with various continents, oceans, and mountains.
Most life-bearing planets had primarily nitrogen and oxygen-based Type I atmospheres; though some (such as Dorin, Gand, and Skako) had unique atmospheres to which their native life forms had adapted. Gas giants, planets made up of primarily gaseous layers, were rarely inhabited, though they were sometimes used for resource collection (such as the Tibanna gas operations on Bespin).
Star Wars Galaxies allows the player to visit various planets of the Star Wars universe.
With new extensions some new planets were added. Most planets can have player cities and also feature planet-specific weather effects e.g sandstorms on Tatooine.

By scientific definition, a planet is any object orbiting a sun with an empty path and sufficient gravity to not tear apart or deform. However, the definition of "planet" used in Transformers context is a bit different. ANYTHING with gravity can be a planet, and oddly, they all seem to be about the same.
Over the course of the many continuities of Transformers, a lot of planets have been encountered, most of them sustaining life. Here are some of the more well-known planets prominently mentioned. It should be noted in some continuities, they are vastly different in atmosphere and gravitational pull, while in others, they're invariably JUST LIKE EARTH.
Some planets are known to be capable of transforming. The two most commonly known are Unicron and Primus. Both were given life at the beginning of time by the One, the sentient core of the universe, or in one case, a puddle of glowing food-goo. Whatever the origins, they are beyond legendary, with their stories heard throughout the universe, and not only by Transformers. The planet Junkion was SUPPOSED to transform, but they probably forgot when they came back from commercial break.
