Galactic Federation - Pleiades Cluster - star Taygeta - planet Erra

This is likely the most Earthlike "alien" world there is. Fifth dimensional of course, which means its reality has another base frequency.

You can safely film an entire Top Gear season there.

If you woke up on that planet you'd think you wound up in some Venus Project mountain retreat in a foreign country.

Probably rural Russia. Temperate parts.
