Earth our home, the third planet of the solar system, harbors diverse life, environment, and is a shelters us Humans, to live, and evolve on.
Biodiversity: Earth is known for its incredibly diverse and complex ecosystems. It harbors a vast array of life forms, ranging from microorganisms to complex multicellular organisms. The variety of species, ecosystems, and environments on Earth is unparalleled in our solar system.
Water, the Blue Planet: Earth is often referred to as the "Blue Planet" because of its abundance of water. Roughly 71% of the Earth's surface is covered in water, primarily in the form of oceans. Water plays a crucial role in shaping the planet's climate, weather patterns, and supporting life as we know it. It is a fundamental element for the existence of life on Earth.
Origin: Earth formed about 4.5 billion years ago as a result of the accretion of dust and gas in the early solar system.
Discovery: Earth was not "discovered" in the same way as other celestial bodies. It has been known to humans for as long as humans have existed.
History: Earth's history spans billions of years, including geological and biological evolution. It has been shaped by various processes, including plate tectonics, erosion, and biological activity.
Orbit Eccentricity: 0.017
Orbit length: The average distance from the Earth to the Sun is about 93 million miles (150 million kilometers).
Rotation: Earth rotates on its axis from west to east.
Rotation length: 24 hours to complete one full rotation on its axis.
Length of Day: 24 hours.
Length of Year: Time to orbit the Sun, approximately 365.25 days.
Escape Velocity: 11,19 km/s
Distance from Sun in AU (Astronomical Unit): 1AU
Spherical Specification: Earth is an oblate spheroid, meaning it is mostly spherical in shape but slightly flattened at the poles and bulging at the equator due to its rotation.
Moon/natural Satellites: Earth has one natural satellite, the Moon.
Rings: Earth does not have any rings.
Gravity: 1
Mass: The mass of Earth is about 5.972 × 10^24 kilograms.
Composition/Structure: Crust, Inner core, Outer core, Mantle: Earth has a layered structure consisting of the crust (solid outer layer), mantle (semi-solid layer beneath the crust), outer core (molten layer), and inner core (solid metal).
Missions: Earth has been the focus of numerous scientific missions, but primarily for studying its environment and ecosystems rather than exploration in the same way as other celestial bodies.
Temperature: Earth's surface temperature varies widely, from extremely cold in polar regions to very hot in equatorial regions. The average global surface temperature is around 15°C (59°F).
Magnetic Field: Earth has a strong global magnetic field generated by the movement of molten iron in its outer core.
North Pole: The North Pole of Earth is the point on the surface of the Northern Hemisphere where the Earth's axis of rotation meets its surface.
South Pole: The South Pole of Earth is the point on the surface of the Southern Hemisphere where the Earth's axis of rotation meets its surface.
Geological environment/Activity (Volcanic, ice, water, Storm, crater): Earth has a diverse range of geological environments, including volcanic regions, icy polar regions, vast oceans, and regions prone to storms. It also has numerous impact craters, although many have eroded over time.
Atmosphere: Earth's atmosphere is primarily composed of nitrogen (about 78%) and oxygen (about 21%) with trace amounts of other gases. It also contains layers such as the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
Size: Earth has a diameter of approximately 12,742 kilometers (7,918 miles).
