When your in the Galaxy screen, if you hover the mouse of the M (for a moon), you will see some numbers. Something like this:
Moon S:8366 T:8
The S stands for the Size of the Moon, and the T is temperature. So in the example above, the moon has a maximum size of 8366, and a temperature of 8.
The temperature on a moon is useless data. It does not affect anything, since the temperature used to calculate how much energy a Solar Sat produces is not that value, but the one on the Overview page.
The size information is important. This tells you how many possible fields a moon can have (derived from a lunar base) and what the chances of a RIP (a deathstar) has in destroying your moon. Deathstars are the only ship that can destroy a moon.
Moon size is a random calculation. There is nothing you can do to control the size of the moon. According to a recent thread on the OGame Forums, you can influence the moon size by creating a larger debris field. A 20% chance at a moon will guarantee a 8,000+ moon size.
Destroying a Moon with a Deathstar
The chance to kill the moon is:
(100-sqrt(moonsize))*sqrt(number of deathstars)
The chance, that the deathstar is killed is:
For now, I am not going to calculate these values. You can do so on your own.
UPDATE: Ok. the calculations above give the following results for my moon.
(100 – sqrt(8366)) * sqrt(1) = 8.5 – Round that to 8%
So a single Deathstar has an an 8% chance of destroying my moon. You would need 140 Deathstars to have a 100% chance of destroying my moon.
However, based on my moon size (of 8366) there is a 45% chance of my moon destroying the Deathstar
(sqrt(8366))/2 = 45.7 or 45%
NOTE: I updated the above function to show the square root (sqrt) instead of Radical. Makes it a bit easier to understand.
How many Fields can a Moon Have?
The calculation for how many fields a moon can have is: (S/1000)^2
In my example above (with my moon), S = 8366, so:
(8366/1000)^2 = 69.989956 = 70 (round up)
I can have 70 fields on my moon. Remember… each Lunar Base adds 4 useable fields to your moon. If you want to keep building more Lunar Bases, you need to save one field from each build. So I would need to build 24 Lunar Bases before I could max out the size of my moon. Considering that each Lunar Base doubles in cost, and a Level 5 Lunar Base costs 320,000 Metal, 640,000 Crystal and 320,000 Deuterium, you can see that having a level 24 Lunar Base is quite out of the picture.
Once you have a moon at a position in the Galaxy, you can never have another moon there. So if that moon was destroyed (either by Deathstars, or by a player deleting a planet) you cannot get another moon there. Not a bigger one, not a smaller moon. NONE!
UPDATE: There USED to be a bug preventing a new moon from forming (assuming you have a debris field adequate), but it is now fixed. So if a moon is destroyed you can get another moon. The next moon is of random size, so it could be bigger… or it could be smaller.
Moons do not aid your main planet in any way during an attack on the main planet. They are very useful as a place to send a fleet or resource quickly to avoid a crash. Just be sure to not leave the fleet and/or resources unattended.
