If you "leave" a planet, does it give you the ability to colonized a new planet or do you have to still do the research.

Research gets expensive, like 8 million metal, 15 million minerals and 8 million gas after 8 planets...

Bruce,
You can have
#Planets, including Special planets = Col.tech. + 1
#Asteroids = Col.tech.
#Moons&Insects = No limit as I know

Deleting some objects - it changes nothing.
Planets, Asteroids Moons&Insects have their own slots.

Highest level of Col.tech. all over the GameWorld is 11
Universe Records
P.S. Bruce,
Do not spam.
