Invasion against orbital protection

So I’m trying to take the homeworld of one of my neighbors and brought two fleets with 7 assault frigates totaling around 200k troops. The problem is whenever I maneuver into orbit to invade it says “planet is protected” and grays out the attack option. How do I bypass or destroy the protection to invade the planet?

New players entering the game get 28 days protection on homeworlds. I’m guessing that the player is new and the HW is still under protection. Any other planet the player may have will not have the same protection.

Also, incidentally, you can’t invade with 2 fleets. The first fleet to do an invasion locks it in. If you want to invade with a larger group (in a single landing), you need a bigger flagship.

Ah thank you I wasn’t aware that there was protection on the homeworld
