Can you destroy a colonized planet?

if you're talking about abandoning one of your colonies, yes.


click the overview link of the colony you want to destroy, click on the name of the colony, it looks like{ Planet "NameOfYourColonyHere" (YourNameHere) }. that will take you to a page with an option to "abandon colony"

No.I mean once I colonize a planet does it mean it's mine until I abandon it? Or can other players destroy it by attacking?

oh.

no, only the owner can destroy a colony on a planet.

Thanks for the info.

I'm gonna start colonizing 1:1:X
