capturing a planet

[wilhil]

Hi

I am playing a large game and not doing to well at the moment, the enemy has taken a very important planet, and rather than destroy it, I want to capture it... I dont really use troops, and just tried, and I have no idea how to do this, I am using the star trek mod,

I tried loading troops in a transport then attacking the planet, getting close, but nothing happened...

I have no idea how to do this, and was wondering if someone can tell me how to attack!

Thanks
