Planet Earth: An Overview Earth is the third planet from the Sun and the only astronomical object known to harbor life. It is the largest of the four terrestrial planets in our solar system and the only place in the universe where liquid water is known to exist in large quantities on the surface. Physical Characteristics Earth is an oblate spheroid, meaning it is mostly spherical but bulges at the equator due to its rotation.

  • Composition: The planet consists of several layers: the crust, the mantle, the outer core, and the inner core. The crust is made of solid rock, while the core is composed primarily of iron and nickel.
  • Surface: Approximately 71% of Earth's surface is covered by oceans, while the remaining 29% consists of continents and islands.
  • Atmosphere: The atmosphere is composed of 78% nitrogen, 21% oxygen, and trace amounts of other gases like argon and carbon dioxide. This mixture protects life by absorbing ultraviolet solar radiation and warming the surface through the greenhouse effect.

Habitability and Life Earth is located within the circumstellar habitable zone (or "Goldilocks Zone"), where the distance from the Sun allows for temperatures that support liquid water. Several factors contribute to its ability to support life:

  1. Magnetic Field: Generated by the motion of the liquid outer core, the magnetosphere shields the planet from harmful solar wind and cosmic radiation.
  2. Plate Tectonics: The movement of Earth's lithospheric plates helps recycle carbon and maintain a stable climate over geological timescales.
  3. Hydrosphere: The presence of water in all three states (solid, liquid, and gas) is vital for all known forms of biological processes.

Orbit and Rotation Earth's movement determines the cycles of time and the change of seasons.

Measurement Value
Rotation Period23 hours, 56 minutes, 4 seconds
Orbital Period365.25 days
Axial Tilt23.4 degrees
Average Distance from Sun~150 million kilometers

The axial tilt is responsible for the seasons; as Earth orbits the Sun, different parts of the planet receive varying amounts of sunlight throughout the year. The Moon Earth has only one natural satellite, the Moon. It is the fifth-largest satellite in the solar system. The Moon’s gravitational pull is responsible for the tides in Earth's oceans and has historically stabilized Earth's axial tilt, which prevents radical climate shifts that could make life difficult to sustain.
