Cybertron

Cybertron is a mechanical planet in the Alpha Centauri system, which is the home planet of the Transformers.

It consists entirely of metallic ores with different physical properties and energon. It is significantly larger than the moon, but smaller than the Earth.

Some characteristics of the planet:

Atmosphere. Cybertron is surrounded by a breathable oxygen atmosphere, suitable for mechanical and most organic life forms.
Rivers and seas. Currently, there are no rivers or seas, but there are oil lakes and even swamps.
Deserts. A significant portion of the planet is covered in deserts, one of which is so vast that it has been called the "Sea of Rust."

The population of Cybertron consists of Transformers, or Cybertronians, powerful robots capable of transforming into various vehicles and other equipment.
