Hi I have a few questions on the way the game works
1) If i share a planet with my legion and one of them occupies it does the planet dissapear from my roster ( the same result as a abandon planet option)

2) If a planet occupied by me is taken over by a enemy does it dissapear from my roster or do i have a time limit to take it back?

3)Does anyone know the formula in which invasion success is?

1) No, you keep the scan.
2) No, theres only 2 ways to "un-scan" a planet, either the owner uses a planet flux, or you use a chart purger. You have all the time in the world until the person who took your planet uses a planet flux.
3) No, Dan likes keeping the equations underwraps.

Here's what I understand about invasion success chance:
- Attack, Defense and Invasion Defense all contribute to your overall Invasion Defense
- Attack power of your ship contributes to your Invasion Attack
- There's been some speculation that crew also plays a role in Invasion Attack
- There's always a chance of failure, even against a planet with 0 defense/attack/invasion defense

yea i thought that was weird i invaded a planet with 30 defense and 20 attack i had a 90% chance of success apparently i failed? lol?

Alright so what is the point of sharing planets with legion members if it dosent purge from your database?

Give planets to legion mates
Defend/Attack planets

If you want a planet removed from your database, first get someone who wants the planet and agree on the terms that a planet flux is used on the planet. Thus, it can be removed from your list.

Sharing uncolonise planet = helping legion mates
Sharing enemy planet = asking for help to weaken it/invade it
Sharing your own = ask to build structures or defend it
