Stratos is the third planet from the Sun in the Tendor system. Despite its similarity in size and mass with Anteria, it is an inhospitable frozen wasteland, hosting an average temperature of below -100 degrees celcius thanks to its high albedo and distance from the Sun, with the frosting on the cake being that its atmosphere has a relatively high concentration of toxic gases in the likes of sulfur dioxide and nitrogen dioxide.

The planet is a terrestrial planet, and is often referred to as Anteria's 'sister planet' due to its similar size and mass, though otherwise they are quite different. It is one of the brighter objects in the night sky thanks to its high albedo caused by its icy surface of frozen carbon dioxide (dry ice), solid hydrocarbons, and water ice. It appears slightly blue-green thanks to the high amount of copper present in the planet's crust, forming a large amount of copper salts and oxides of the color that mixes with the other constituents of its surface. Lakes and seas of light hydrocarbons are present on the surface of the planet, though it likely does not host any extraterrestrial life.

Despite its inhospitability, it is still one of the more prominent celestial bodies that Anterians wish to colonize within the near future thanks to its relative proximity, though it is quite likely that colonies would instead be constructed on one of its two substantial moons first, being easier to use as stepping stones for further exploration than Stratos, having an atmosphere over two and a half times thicker than on Anteria.
