Your First Planet

Your planet is your home base — everything you build, research, and produce starts here. Understanding how planets work is the foundation of your galactic empire.

What is a Planet?

In Age of Space, a planet is your primary base of operations. Every player starts with one planet — a world floating in a solar system within a galaxy. This is where you build mines to produce resources, construct research labs, shipyards, and defenses.

Each planet has a limited number of building fields (also called "slots"). Think of them as plots of land. Each building you construct occupies one field, so you must plan carefully which buildings to place and how high to upgrade them.

Your starting planet has a random number of fields determined by its size. Larger planets have more fields, giving you more room to build. Later in the game, you can colonize additional planets with potentially more fields.

The Planet Surface

The planet surface is the main view you interact with. It displays a grid of slots where your buildings are placed. Empty slots appear as open terrain, while occupied slots show the 3D model of the building constructed there.

To build something, click on any empty slot. A modal will appear showing all buildings available for construction, along with their costs and requirements. Buildings that you don't meet the requirements for will appear locked.

Your planet surface — click on empty slots (highlighted with a cyan glow) to build new structures.

To upgrade or interact with an existing building, simply click on it. You'll see options to upgrade to the next level (with costs displayed), view production details, or access building-specific features.

Naming Your Planet

Your planet starts with the default name "New Planet." You can change it at any time by clicking on the planet name in the interface or through the Command Center.

Choosing a good name helps you stay organized, especially once you have multiple planets. Some players name planets by their purpose (e.g., "Mining Hub," "War Base"), by position, or with creative lore-friendly names.

Naming Tip

When you have multiple planets, a naming convention helps enormously. Try numbering them (Planet-1, Planet-2) or naming by function (Mines, Fleet, Defense) so you always know which planet serves which purpose.

Understanding Planet Fields

Every planet has a maximum number of fields that determines how many buildings you can place. Your starting planet typically has between 140 and 250 fields. Each building level occupies one field.

For example, a Titanium Mine at level 10 occupies 10 fields (one for each level). This means upgrading buildings uses more and more of your limited space.

You can check your planet's field usage in the Command Center. It shows your current used fields versus the total available. Once you've used all fields, you cannot build or upgrade anything further on that planet.

Used Fields = Sum of all Building Levels

Each building level occupies exactly 1 field. Total used fields = sum of all building levels on the planet.

Example: If you have Titanium Mine Lv.10, Graphene Mine Lv.8, and Solar Plant Lv.9, that's 10 + 8 + 9 = 27 fields used.

Planet Positions in a Solar System

Each solar system contains 15 planet positions, numbered 1 through 15. The position of your planet within the solar system affects several important factors:

Position	Type	Characteristics
1-3	Positions 1-3 (Inner): Closest to the star. Higher temperatures mean more solar energy from Solar Plants, but less Deuterium production. Planets tend to be smaller.
4-6	Positions 4-6 (Middle-Inner): Good balance of temperature and planet size. Positions 4-6 often have the largest planets with the most fields.
7-9	Positions 7-9 (Middle): Balanced temperature. Good for all-around planets. Position 8 is often considered ideal for colonies.
10-12	Positions 10-12 (Middle-Outer): Cooler temperatures boost Deuterium production. Planet sizes are still reasonable.
13-15	Positions 13-15 (Outer): Coldest positions. Best Deuterium production but lowest solar energy. Smaller planet sizes.

Your starting planet is assigned a random position. You cannot change it, but understanding positions helps when choosing where to colonize later.

This value may vary depending on the universe settings.

Your Command Center

The Command Center is the first building on every planet. It serves as your planet's control hub, displaying vital information at a glance.

Inside the Command Center, you can:

View and change your planet's name
See your planet's coordinates (Galaxy:System:Position)
Check your total and used building fields
View your planet's temperature range
See the planet's diameter and orbit details

The Command Center modal showing planet details — your hub for planet management.

The Command Center does not need to be upgraded — it automatically provides all planet information. It's always the first building placed when you colonize a new planet.

Tips for Managing Your Planet

Plan Your Fields

Don't randomly upgrade buildings. Think about which buildings you actually need at high levels. Mines are always worth upgrading, but utility buildings may not need to go as high.

Use the Tutorial

The in-game tutorial walks you through your first buildings step by step and gives rewards. It's the fastest way to get your planet up and running.

Don't Delete Your First Planet

It may be tempting to restart with a better position, but your first planet already has progress. It's better to colonize a well-positioned second planet later and transfer operations.

When you unlock the Astrophysics technology and Colony Ships, you can colonize new planets. Choosing the right position is crucial for maximizing fields:

Positions 4-6 and 8-10 tend to generate the largest planets (200-300+ fields).
Position 8 is widely considered the best overall colonization position — large planet size with balanced temperature.
For dedicated Deuterium farms, positions 13-15 give the highest Deuterium production due to cold temperatures.

Temperature directly affects Deuterium Synthesizer output. Colder planets produce more Deuterium per hour at the same mine level. The formula includes a temperature factor that increases production at lower temperatures.

If you colonize a planet and get a small size, you can abandon it and try again. Abandoning a planet deletes all buildings and resources on it, but frees the slot for re-colonization. Be patient — a large planet is worth multiple attempts.

Requirement: Astrophysics Level 1

Frequently Asked Questions

No. Once a planet is placed, its position is permanent. However, you can abandon a colony (not your home planet) and colonize a new one at a different position.

The maximum number of planets depends on your Astrophysics research level. Each odd level of Astrophysics grants one additional planet slot, up to a maximum that varies by universe settings.

You won't be able to construct new buildings or upgrade existing ones. You'll need to carefully choose which buildings to demolish or focus your remaining upgrades on the most important ones. Alternatively, build more infrastructure on other planets.

Yes! You can downgrade or demolish buildings through the building menu. Each level demolished frees one field. Be careful though — demolishing mines reduces your income permanently.
