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.
- Specialty buildings: Oracle and Warp Gate.
- Oracles cannot scan Moons, so transports and attacks from Moons are safe from having the return trip Oracle locked.
- Resources may be stored and consumed via a Shipyard. Since Mines cannot be built, resources resting on a moon never interfere with mine production.
- Anti-Ballistic Missiles from Missile Silos built on the planet will defend the moon’s defenses if it is attacked with Interplanetary Ballistic Missiles.
- Building on a Moon is expensive due to the requirement to build Lunar Bases.
- Mines cannot be built.
- Missions cannot be operated from the Moon.
- Ships in orbit around a Moon are not hidden from view by probes.
- Workers cannot be transported to, built on, or used on a Moon.
- Foundries cannot be built.
- Research Labs cannot be built.
- The Merchant will not operate on a Moon.
- Debris caused by a battle taking place at a Moon will be found adjacent to the associated planet, not the Moon itself.
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), unless a Lunar Architect is used and then the percentage is doubled. 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. Moon creation is immediate after the battle, and does not consume the debris field; therefore, collecting the debris field will not interfere with the process. Moons generate with exactly 1 (one) building field, which must be used for a Lunar Base Level 1.
- Lunar Base is required in order to build other structures on a moon. Each level provides three additional building fields on the moon, but occupies one, leaving a surplus of two available building fields.
- 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. Building one allows you to build ships and defenses.
- Capitol works like a capitol on a planet.
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. Anti-Ballistic Missiles (ABMs) located on a player's planet will also defend defenses built on that planet's moon.
At any time, should you have used all current building fields, you will receive the following warning on the moon's Buildings page:
All fields on the moon have been used up. If you wish to continue building, you will have to tear down one building's level and then upgrade the Lunar Base to gain more fields.

- 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)
The probability of getting a moon is always a maximum of 20% on any given chance, unless a Lunar Architect is used and the chance is doubled. 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.

In Starfleet Commander Nova, moons are assigned a size at the time of formation based on the size of the debris which created it.
Moonsize Diameter: = FLOOR ( (x + 3 * Base Moon Percentage Chance ) ^ 0,5 * 1000 ) x is a number between 10-20 (10 <= x <= 20) where all x are equally likely to occur
The minimum diameter is 3,605 and the maximum diameter is 8,944. You should always seek the largest possible moon, so it will not be easily destroyed. At the highest probability of 20% moon formation a moon always receives a diameter of at least 8,366.

MinimumPossible lunar sizes
The Moon Chance portion of the formula for moon size does NOT take into consideration the lunar architect.
In Starfleet Commander Nova a moon can be destroyed by a fleet of Zeus. Before Zeus can destroy a moon, they must defeat all fleets and defenses on the moon. There are 4 possible outcomes for a moon destruction mission:
- Moon survives, Fleet survives
- Moon survives, Fleet is destroyed
- Moon is destroyed, Fleet is destroyed
- Moon is destroyed, Fleet survives
If the fleet is destroyed a debris field is created but there is no moon formation chance. If the moon is destroyed all fleet tasks from it will be diverted to the planet.
Formulas for Destruction
There is almost always a greater chance that a fleet with a single Zeus will be destroyed than the moon. Adding Zeus raises the probability that the moon will be destroyed, up to 100%. However, assuming defending units on a moon can be defeated by a single Zeus and there is no limit on the number of attempts that can be made, additional per-attempt Zeus increase the expected cost of moon destruction.
In the following table
- Moon Sizes are selected from the outside (left and lower) edges of the above moon size table. These values are generally repeated several times in the interior as well.
- The Chance of Fleet Destruction is the chance that the fleet is destroyed in a particular attempt, as given in the above formula. It is independent of fleet composition.
- The Expected Attempts for Single Zeus is the expected (average) number of times a single Zeus would have to attempt moon destruction before the moon is destroyed. (As it turns out) it is simply the inverse of the above chance to destroy moon with Zeus = 1. This is by no means a guarantee; as the number of attempts required with a given number of Zeus follows a geometric distribution, the variance is very large. It can only be said that the actual number of attempts required will usually be between 1 and twice the expected value listed in this column.
- The Expected Zeus Lost Using Single Zeus is the product of the previous two columns, multiplying the expected number of attempts by the probability that the Zeus will be lost in each attempt.
- Zeus required for Certainty is ⌈(100÷(100 − MoonSize½))2⌉, the number of Zeus required for the chance to destroy moon to meet or exceed 100%.
- Expected Zeus Lost at Certainty is the product of the second and fifth columns, multiplying the chance of fleet loss by the number of Zeus in a fleet that has 100% chance of destroying a moon of that size. Actual fleet loss is, of course, all or nothing.
