Moon

A moon is a celestial body that can be found in orbit around an inhabited planet. It is the home of several specialty buildings, and can be used in many similar ways to a colonized planet. It disappears upon abandoning a planet, or when a colony is removed for inactivity.

Evaluation

Advantages

• Specialty buildings: Oracle and Warp Gate.
• Other oracles cannot scan moons.
• Resources may be stored and consumed via a Shipyard.
• Cannot be destroyed.
• Ships parked at the moon are invisible to espionage probes

Disadvantages

• Mines cannot be built.
• Missions cannot be operated from the moon.

Formation

Moons can only be formed from the debris of large battles. For every 150,000 debris produced in a battle, there is a 1% chance that a moon will coalesce. The maximum chance of moon accretion is 20% (3,000,000 debris).

The calculation is performed on a per-battle basis; any debris in orbit at the time of a battle is not included in determining if a moon is formed.

Because the moon is the result of battle, the defending planet is the owner of any moon that is formed.

Moons generate with exactly 1 (one) building field, which must be used for a Lunar Base Level 1.

Buildings

• Lunar Base is required in order to build other structures on a moon. Each rank provides three additional building fields on the moon.
• Oracle can only be built on a moon. It is a long range telescope that is capable of detecting most fleet movements.
• Warp Gate can only be built on a moon. When you have more than one, it allows for the owner to instantly transfer ships between warp gates.
• Shipyard works like a shipyard on a planet works. Building one allows you to build ships and defenses.
• Capitol works like a capitol on a planet works.

Note that the moon is considered a separate entity from the planet it orbits. Any shipyards, planetary defenses, and capitols built on one do not affect build times and defensive capacities of the other. However, it has been reported that Anti-ballistic Missiles built on a planet may also protect its moon.

• NOTE: The rightmost columns project the rounding from the 1% value and so overstate the requirement slightly (8.3 Athena for 1% is indeed 9, but at 20% the correct answer is 167 not 180)

Probability

The probability of getting a moon is always a maximum of 20% on any given chance. The more attempts you make however, the greater the likelihood you will succeed in creating a moon. Unfortunately five 20% attempts will not guarantee you a moon; the odds of probability are closer to 67%. The same can be said with 21 20% attempts. Even though the odds of probability state you have a 99% chance of gaining a moon, every attempt still has a 20% chance of creating a moon.

Keep in mind that the chance is always random. The game doesn't keep track and calculate how many attempts you've made in the past. Below is a chart that outlines the probability.
