Most interesting facts about the earth

The Earth

  • The Only planet of our Solar system where life exists.
  • The Earth also called ‘Blue Planet’.
  • Circumference: 40008 s km (polar) and equatorial Circumference 40075 km.
  • The area is nearly 510 million sq. Km.
  • The 5th largest planet of our Solar system.
  • Perigee: The Nearest position of Earth to Moon (356000 km
  • Apogee: The Farthest position of Earth from the moon (407000 km).
  • Aphelion: The Farthest position of Earth from Sun on July 4, about 152 million km.
  • Perihelion: The Nearest position of Earth to Sun on January 3, about 147 million km.

The shape of the Earth

The Earth is an oblate spheroid, a sphere flattened along the axis from pole to pole such that there is a bulge around the equator. Earth bulges at the equator and is flattened at the poles.

Geoid
The shape of the Earth is also called “Geoid“. At the equator, our weight will be less and when we are at poles our weight will be more. Geodesy is a branch of science which deals with measuring the Earth’s size and shape.

Equinoxes

  • These are the days when the days and nights are equal. Under this situation, the Sun is vertically overhead at the equator. It happens in two days of the year i.e. 21st March and 23rd September.
  • 21st March Vernal Equinox.
  • 23rd September Autumnal Equinox.
