Venus

Venus is the hottest planet in the Solar System.

**Location:** Milky Way Galaxy/Local Cavity/Solar System

**World Categories:** Pressure-Cooker World

**Venus** is the second planet from Sol and the third largest terrestrial body in the Solar System. It is named after the Roman goddess of love and beauty. Venus orbits the Sun every 224.7 Earth days. With a day/night cycle of 243 Earth days, it longest day/night cycle in the Solar System. On Venus Sun rises in the west and sets in the east because Venus rotates around its axis backward, the only other planet in the system with backward axis rotation is Uranus. Venus did not have any moons until 2244, but it captured a passing asteroid that year and became in possession of a natural satellite, this event was observed by Venus orbital research station, leaving only Mercury without a moon.

Venus is also the first place that humanity found an active biosphere.

## Planetary Properties

Venus is one of the five terrestrial planets in the Solar System. It is similar to Earth in size and mass, and is often described as Earth's "sister" or "twin". The diameter of Venus is 12,103.6 km (7,520.8 mi)—only 638.4 km (396.7 mi) less than Earth's and its mass is 81.5% of Earth's. Conditions on the Venusian surface differ radically from those on Earth because its crushing atmosphere is 96.5% carbon dioxide, with most of the remaining 3.5% being nitrogen. The surface temperature is 737 K (464 °C; 867 °F).

### Geology

Much of the Venusian surface appears to have been shaped by volcanic activity. Venus has several times as many volcanoes as Earth, and it has 167 large volcanoes that are over 100 km (60 mi) across. The only volcanic complex of this size on Earth is the Big Island of Hawaii. This is not because Venus is more volcanically active than Earth, but because its crust is older. Earth's oceanic crust is continually recycled by subduction at the boundaries of tectonic plates, and has an average age of about a hundred million years, whereas the Venusian surface is estimated to be 300–600 million years old.

### Atmosphere

Venus has an extremely dense atmosphere composed of 96.5% carbon dioxide, 3.5% nitrogen and traces of other gases including sulfur dioxide. The mass of its atmosphere is 93 times that of Earth's, whereas the pressure at its surface is about 92 times that at Earth's—a pressure equivalent to that at a depth of nearly 1 km (5⁄8 mi) under Earth's oceans.

Venetian atmosphere generates the strongest greenhouse effect in the Solar System, creating surface temperatures of at least 735 K (462 °C; 864 °F). This makes the Venetian surface hotter than Mercury's, which has a minimum surface temperature of 53 K (−220 °C; −364 °F) and maximum surface temperature of 700 K (427 °C; 801 °F), even though Venus is nearly twice Mercury's distance from the Sun and thus receives only 25% of Mercury's solar irradiance.

### Natural Satellite

Venus did not have any natural satellite until 2244, but it captured an asteroid as its moon that year. in 2245, the name Inferno was chosen for Venus first natural satellite.

Inferno has a radius of 14 km (8 mi) and orbits around Venus every 15 days. Inferno has a massive gold reserve valued at 400 billion USD and some space mining companies are trying to earn the right to mine Inferno, so far with no success. Inferno will crash into Venus in the next 5 million years, suggested by its orbital pattern.

## Biosphere

*Main Article: **Life on Venus***

Life on Venus was hypothesized to exist by Heinz Haber in 1950 and was discovered in 2038 by **Aspiration**, a probe designed to collect and analyze Venetian atmosphere. There is only two types of thermoacidophilic extremophile microorganisms that lives in the acidic clouds of Venus in an of altitude 51 km to 58 km.

## Colonial Development

Characteristics of the planet Venus has helped with some colonial development in the Venetian sector. First of these being its Deuterium-rich atmosphere which led to development of collection outposts in its orbit, and the second being the a weak magnetic field, which attracts high-precision electronics development to the planet.

Venus has a population of 7000 people on its surface. Venus largest city, Alta, has a population of 5000 people and sits at the Venetian south pole.
