  • Earth orbits around the Sun in 365.25 days. 0.25 days add to form 1 day after 4 years resulting into the leap year.

  • Earth completes its rotation about its axis in 23.9 days, defining days and nights.

  • Earth's axis of rotation is 23.5 degrees inclined from the normal to the elliptical equatorial plane of planets, giving rise to the seasons on the planet.

  • On two days of the year- Equinoxes, both the hemisphere is equally illuminated by the Sun.

  • Whichever hemisphere is close to the Sun experiences summer, while the one away from the Sun experiences winter.

  • The reason why India and Australia experience complete different season is due to the inclination of Earth about its axis.
