Earth

## Cross Section

The human home planet, of course.

Its cross-section is very close to the actual theorized layout of the Earth's layers with the thin crust, majority mantle, and the inner and outer cores. It has a population of 7.791 billion (previously 7.788 billion).

## Populations

Its population map is realistically designed - for example, the U.S.A has a little over 330 million deaths when burned (which matches the population now, or at least when the most current version was released), the U.K. has 66 million deaths when burned (exact U.K. population when rounded), India has over 1.35 billion deaths when burned (correct again), and China has over 1.39 billion deaths when burned (correct yet again). Very small city lights, that have cities with less than 1 million people, are not counted in the death count, even though there are people there. This makes it possible to have 0 million people alive, yet with city lights still on (i.e. not broken down , or all land voxels removed), simply because they were not counted in the statistics/population map.

## Defense Systems

The approximate location of Washington D.C., the capital of the U.S.A., and the approximate location of Moscow, the capital of Russia, both act as defense points for Earth against a UFO  (and possibly other ships' ) attack by sending nukes  to the spaceships  before they can attack within a radius. They can send multiple nukes  at once within a radius similar to the size of the singed area left by a successful spaceship ((usually ), but also ) blast, but can be too late when having to send nukes  to the outer edges of that radius, as spaceships  can have already shot (or player-fired nukes  may destroy the surrounding area first) before being destroyed, which destroys the capital. (Other weapons  - / - , etc. can also destroy the capital as well, before the ships  attack.)

### Flat Earth

    Using the LASER  (preferably set  to 5 power) to destroy most of the northern and southern hemispheres, to leave a disk-like remnant, then resetting  the planet, will make the Earth File:Earth.png Flat . Alternatively, set the grid so that only two axes are full. This will leave a disk-shaped remnant. Reset to flatten it. It's cross-section is massively changed compared to the standard round Earth File:Earth.png, it's population is changed to 500m (very easy to kill all populations ), and there are 3 main issues:

1. The Laser Satellite  will start cutting at the central north pole, then cut more away before crashing into the planet. If used directly on the side, they will fire  and scrape off some of the planet's surface (the LASER  just touches the surface voxels, barely), then stop.
2. The UFO  can not effectively fire at anywhere other than the Arctic Circle. (It will also crash into the planet.) If used from far away (likely from stopping behind a moon , or even Flat Earth's moon , then
3. The ForceField  does not defend correctly (shields  will pop up sideways, like a dome shape, just like the atmosphere.).

    In newer versions, the Sun  and the Moon  are positioned directly above the Flat Earth. They are slightly different in operation, however:

Using the lasers  -  on the Sun  will invoke a Supernova, but instead of breaking down  and exploding , Flat Earth will just go dark and turn on all city lights.  The Sun , obviously being a source of heat, will also burn Flat Earth File:Flatearthburned.png if touched and moved off its normal position (it can fall down due to gravity , or more likely, being pushed (can be from any weapon) , etc.) The same reaction applies for the Moon , though being far less massive, it may just fly off course, with a small explosion File:Explosion-small.png. This moon  is a solid object, unable to be damaged like most other voxel-based planets. It will also damage Flat Earth  if it hits it, though with a much smaller impact radius than the Sun , and is also far smaller than the weapon Moon  (a quarter its size, in fact.)

### Donut Earth

    A donut-shaped Earth (formerly just called **Donut**) is available by cutting the Earth into a donut shape. It only has a population of approx. 3 billion, and the continents curve inwards.

To unlock this shape, use the same grid settings (two axes full/a flat plane) for the Flat Earth. However, after this, cut a hole in the center, big enough to be considered a donut's hole. Reset to get the donut-shaped Earth.

### Cube Earth

    A cube-shaped Earth (formerly called **Cube *World***) is available in the menu, even after the game has just been installed (for the newest versions). Originally, it would have been presumably unlocked by cutting Earth into a cube, but the developers probably scrapped the idea, in favour of a perpetually-unlocked Cube Earth (it has been reinstated now).

Using the grid feature set x,y,z to the middle of the bar then put them down 1 (or half), from there just destroy the earth's unprotected areas, as everything in the grid is protected and so will not be damaged. Once it is a cube make sure it's all flat (cut away any small lumps), and then reset the planet.

### Trick Or Treat

    A planet size pumpkin released as part of the halloween update. It is available in the “Unknown System” (question mark, ?) planet tab  and can be unlocked by either using the Planet Killer  weapon or exploding the sun  in a Supernova while on the Earth File:Earth.png planet (use a laser  - .). After one of them are chosen, wait until the planet is glowing bright orange, and before it explodes , reset the planet to get the pumpkin planet. It has a sun  of its own inside, but will explode in a Supernova harmlessly if lasered  - .

## Trivia

* Its population map is realistically designed.
	+ The USA has a little over 330 million deaths when burned (which matches the population now, or at least when the most current version was released), the U.K. has 66 million (exact U.K. population when rounded), India has over 1.35 billion, and China has over 1.39 billion deaths.
* Small cities with less then 1 million people aren't counted in the death count, this makes it possible to have 0 million people alive with city lights still on.
* Earth can be used as a weapon (as a Moon) on gas giant planets. /
* The 2100 Earth variant also has the defense points in the USA and Russia.
