Key Facts & Information

Planet Earth Profile

  • Mass: 5.97 x 10^24 kg
  • Polar Diameter: 12,714 km
  • Equatorial Diameter: 12,756 km
  • Moons: 1
  • Orbit Period: 365.24 Days
  • Distance from the Sun: 150 million km
  • Earth was formed around 4.54 billion years ago. It is the only planet in the solar system that was not named after a mythological god or goddess.
  • Earth orbits the sun in 365.24 days, at the same time it spins on an imaginary line from the North pole to South pole called an axis. Earth needs 23.439 hours to rotate on its own axis. Moreover, its rotation is tilted to an ecliptic plane. As a result, there are times in a year that the northern and southern hemispheres are pointing towards and away from the sun giving us different seasons.
  • Twice a year, tilting of the Earth in relation to the sun results in equinoxes (Autumnal & Vernal), meaning there are almost equal amount of day and night in all latitude.
  • When the Earth is tilted towards the sun at its maximum, the summer solstice occurs, giving countries north of the Tropic of Cancer the longest day of the year.
  • During the winter solstice, all countries south of the equator experience the longest night and shortest day of the year.
  • All planetary orbits are in oval-shaped ellipses.

Earth’s Formation and Composition

  • There are many theories about the Earth’s formation, one of the most popular is that it came from a collapsed solar nebula, or rotating cloud of gas and dust.
  • Earth’s history is divided into four eons, namely Hadean, Archean, Proterozoic and Phanerozoic.
  • The last of the four eons is divided into three eras including Paleozoic, Mesozoic and Cenozoic. The Paleozoic era is characterized by the development and existence of invertebrate animals and plants living in the seas and on land, while the Mesozoic era is also known as the Age of Dinosaurs, and the Cenozoic era is the age of mammals.
  • Earth’s atmosphere is composed of 78% nitrogen, 21% oxygen, as well as water, carbon dioxide, argon and other gases. Among other planets, Earth is the only planet with oxygen, making it viable to support life as we know it. It is layered into the thermosphere, or the hottest region of the atmosphere; mesosphere, the coldest region, which protects Earth from meteors; stratosphere, which contains most of the oxygen and contains the ozone layer; and the troposphere region that touches the Earth.
  • Earth’s interior structure is made up of the inner core, outer core, mantle, and crust.
  • Today, scientists have identified about 2 million species of life, but they think that it may exceed between 5 to 10 million.
  • Earth is mapped into 7 continents comprising hundreds of countries, seas, oceans and landforms.
