Mercury

## Paradise Habitability

> *Named for the quick-footed messenger of the classical Roman gods, the planet Mercury is a heat-blasted rock orbiting closer than any other to our Sun.
>
> With a daily temperature cycle of over 700 K, Mercury experiences greater temperature extremes than any other body in the solar system. Interestingly, though, the planet spins so slowly that it would be possible to walk in twilight forever, keeping pace with the sunrise in the relatively mild pre-dawn temperatures.*

## About

**Mercury** is the first planet from the Sun and one of the five free-to-play worlds in TerraGenesis, the Terrestrial Planets. It is a hot and scorching world with no atmosphere.

## Strategy

Mercury is one of the most straightforward planets to terraform in the game. It doesn't have a crushing atmosphere, enough vapor to flood the planet, a tiny surface area that barely fits any cities (like the Moon) or an already established civilization facing impending doom (like Earth). Sure, Mercury is hot, but the heat doesn't seem to affect the cities in any way, not like Venus's atmosphere that occasionally crushes the buildings in Random Events.

Just slowly start building cities, increasing Revenue, and then can calmly terraform Mercury into a new home for humanity.

## Notes

Do not use Solar Shades because they spend Credits. Try Aerostat Platforms because they generate Credits. For water, can use Aquifer Networks, but be careful because too many will flood **Mercury** entirely. For oxygen, build some CyanoVats or oxygen plants. What some players recommend, however, is to terraform the rest of Mercury’s stats (pressure, oxygen and water) and built the Soletta to fix the temperature.

AtmoGen Suites can increase oxygen levels in the air for a little bit but CyanoVats can decrease pressure, so build some thermal dusts. On the other hand, Aquifer Networks can increase Pressure, so build some Sequestration Plants and wait until it is upgraded to Level X. Build silver, palladium and rhodium mines since, they generate a lot of revenue.

**Mercury** has a lot more suitable places to put Cities than other planets (except for the poles, which are at a low elevation); see the elevation on map below:

## Live Event Features

## Trivia

* Mercury is the messenger of the gods and son of Jupiter in Roman mythology.

* Mercury has almost no atmosphere, meaning that its temperature wavers from 700 K (427 ºC) to a frigid 105 K (-178 ºC) in the night due to the lack of atmosphere not trapping the heat. It has an average temperature of 440 K (167 ºC)
* Mercury is the smallest planet in the solar system, at only 4880 km in diameter. If put the rest of its layers and its atmosphere, its diameter will be about 6 to 8 jupiters!

* Mercury has little room for stable orbits, due to the sun's gravitational influence and its small hill sphere ( area where a planet’s gravity is stronger than its star (or any orbiting object for that matter)). Mercury has no moons, largely due to its small hill sphere, which about 175 thousand kilometers, about ⅓ the distance between the Earth and the Moon.

* Mercury is one of the three worlds that one can play without spending any money or finishing other planets. The other two that are unlocked at the beginning of a play though are Mars and the Moon.

* Mercury has a very thin atmosphere composed of oxygen, sodium, hydrogen, helium, and potassium.

* Mercury has a large outer core and inner core, but a relatively thin mantle and crust compared to other planets. In fact, it’s core produces a magnetic field. An unknown process causes Mercury to shrink.

* The developers set Mercury's temperature to 720 K, which is hotter than its highest recorded temperature of 700 K. The average temperature of Mercury is about 440 K.
