Moon

A moon can exist on any planet in the universe. They are created by chance if a large enough battle occurs at a planet. Moons can also be destroyed by Deathstars. A moon is extremely important, foremost in allowing a safe fleetsave.

In addition, moons are the only locations where certain facilities can be built. These include the Sensor Phalanx and Jump Gate. Due to the importance of having a moon, many players engage in moonshots in order to try to create one artificially.

Once created a moon functions sort of like an auxiliary planet. It can send and receive fleets, hold resources, be attacked, and so forth. The travel distance between a moon and planet it orbits is naturally very short.

Facilities[edit | edit source]

The following buildings can be constructed on a moon:

A moon starts with only 1 field. The Lunar Base is used to add more fields to a moon. Each level adds three field but of course consumes one.

You cannot build resource mines, Research Labs, Nanite Factories, Terraformers, or Missile Silos on a moon.

Notes[edit | edit source]

↑ ^1.0 ^1.1 ^1.2 The storage is useful only for scrap merchant, and that is hardly enough reason to build it and waste slots.

Defense[edit | edit source]

As long as the required Shipyard level is constructed, any Defenses can be built on a moon. Just like on a Planet, constructed defenses do not use up fields. IPMs can be used to destroy defenses on a moon. While it is not possible to build ABMs on the moon the ones from the planet will defend the moon if attacked by IPMs.

Obtaining[edit | edit source]

Having a moon is so desirable for success in OGame that many players team up to organize a series of moonshots until they get one. Because the largest default chance any single attack can have at forming a moon is 20%, it can often take many moonshots in order for a moon to form on the desired planet.

Destroying[edit | edit source]

A moon can be destroyed by a fleet of Deathstars. If there is any fleet or defense, the attacker must win the battle first before the moon destruction chance begins. A draw or loss by the attacker will send any surviving Deathstars back with no moon destruction. Regardless of if the moon is destroyed or not, there is a chance that the moon will destroy the Deathstars. The formulae are provided below. It is important to note that when a Moon, the Deathstars, or both are destroyed there is no debris field created in the moon destruction mission.

Moon Destruction Results[edit | edit source]

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

Fleets returning to the destroyed moon will be rerouted to the planet. This will mean the fleet would be visible to a phalanx.

Formulae[edit | edit source]

Key:
S = Size of the moon (Km)
D = number of Deathstars

Chance to destroy moon (in percentage): $(100-{\sqrt {S}})\times {\sqrt {D}})$

Chance the deathstar is destroyed (in percentage)^{[note2 1]}: ${\frac {\sqrt {S}}{2}}$ ^{[note2 2]}

Notes[edit | edit source]

↑ this is a single roll for the entire fleet.
↑ Before deathstars destroy a moon, they have to fight with fleets and defences on the moon. There is almost always a greater chance that the deathstar(s) will be destroyed than the moon - however, take for example a size 8944 moon being attacked by 100 deathstars. There is a 54.27% chance that the moon will be destroyed yet a 47.29% chance the deathstars will be destroyed. Additionally, any number of deathstars greater than 339 causes a claimed chance greater than 100% of moon destruction.
