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.

Special Note

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), 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.

Buildings

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.

Probability

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.

Moon Size

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.

The Moon Chance portion of the formula for moon size does NOT take into consideration the lunar architect.

Moon Destruction

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:

  1. Moon survives, Fleet survives
  2. Moon survives, Fleet is destroyed
  3. Moon is destroyed, Fleet is destroyed
  4. 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

Chance to destroy moon (in percentage)= Moondestroyformula.png


Chance the Fleet is destroyed (in percentage)= Fleetdestroyformula.png


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.
