Earth

General Description
Earth is the homeworld of the human species and the capital of "United Systems of Milky Way", located in the Solar System. It is the namesake of the Earth-Like World classification of Terrestrial Planets. It is the

third planet of the system, orbiting at precisely 1 AU from its parent star, a G2-V Main Sequence star known The Sun. Earth is the largest of the system's terrestrial and rocky bodies. The planet and its single moon were born from an accretion disk that existed during the Sol System's formation, which happened around 4.5 billion years ago. It has one natural satellite, known simply as "The Moon", or less commonly as "Luna".

Atmosphere
Earth's atmosphere is composed primarily of Nitrogen, Oxygen, Argon, Carbon Dioxide and Water Vapour. The composition of its atmosphere is essential to life, as all organic life on the planet relies on the Nitrogen and Oxygen to survive. Plant life relies on Carbon Dioxide so they can make their own food and maintain the Oxygen in the atmosphere for animal life. Without an atmosphere, Earth would be uninhabitable and would have no oceans.

Temperature
The temperature on earth can range between cold and warm due to it having seasons, the regular temperature during summer is about 303 K(30°C), and during winter its 258 K(-15°C). The coldest recorded temperature is (183 K)-89.2°C and the hottest is 303 K(55°C).

Orbit
Earth makes a complete orbit around the Sun in 365 Earth days. Its orbit around the Sun is the mostly circular. It is about 1.0 AU from the Sun.

Rotation
Earth makes one rotation in 24 hours, making it relatively fast spinning. Days are mostly regarded as Earth Days, for example one Venus rotation is 10.1 Earth Days.

Geography
70% of Earth's surface is made up of liquid water, an ingredient essential to life. The remaining 30% is land, which is divided into 7 continents (Africa, Antarctica, Asia, Australia, Europe, North America, South America). Most of the planet's land area has been taken over by humans and their cities but wild areas still remain. Earth's terrain is very diverse, featuring all kinds of biomes from snowy peaks to hot deserts.

Flora
Plant life also knows as flora exists nearly everywhere on the ground. Grass is the most common and can be easily found in fields and plains. These plants are responsible for maintaining the planet's Oxygen-rich atmosphere by absorbing carbon dioxide and releasing oxygen, in a process called Photosynthesis. Plant life is the most common type of life on Earth. They lack consciousness unlike most animal life, but are living nonetheless.
