Protos
Protos is a small moon orbiting the ancient planet Methuselah.
Fiction
3H comics
Protos was created by Primus billions of years ago as a prototype and dry run for the creation of Cybertron. For 300,000 years, part of Primus's essence reshaped Protos from the inside out, creating a self-sufficient hive-like colony, the Sanctuary, and then creating life, the first twelve Transformers.
Orbitally locked 'behind' the larger planet, Protos only sees brief moments of sunrise, many years apart. It is a cobalt-colored world with corrosive gases, raging seas of nucleon that mutate mechanical life, showers of shrapnel-like ice needles, and caustic windstorms. Protos is the most inhospitable environment imaginable, cloaked in near-absolute darkness, locked in the shadow of a giant planet that shields it from view. Few know it exists, even fewer have visited. Covenant

TransTech
In the wake of the descent of the Shroud, TransTech Minister of Higher Dimensional Sciences Rhinox proposed to create a Large Pulsar Array in the vicinity of Protos to create a Hyperwave dimensional-oscillation generator in order to restore Axiom Nexus's transdimensional capabilities.

Note
- In an answer given in the Facebook version of Ask Vector Prime, Vector Prime claims that Primacron's lab was located on Protos in The Transformers cartoon, and that the ancient planet seen in "Call of the Primitives" was Methuselah. While the latter is certainly possible, the idea of Primacron's lab being on Protos is factually untrue as, in the episode, the lab was only ever depicted as a small spacefaring vessel free to roam the cosmos with Primacron as its pilot (even in the flashback to Unicron's creation) and never as part of a moon like Protos. Either Vector Prime knows something about Primacron's lab that we don't known (and doesn't let on about it) or he was simply mistaken.
