  • The sun is the central star of the solar system, around which all the planets and other celestial bodies revolve in elliptical orbits.
  • The sun is the main source of energy for the solar system, as it produces heat and light through nuclear fusion reactions in its core.
  • The sun is also responsible for the seasons, day and night, and climate on earth and other planets, as it influences their rotation and revolution, as well as their axial tilt and orbital eccentricity.
  • The sun also affects the magnetic fields of the earth and other planets, as well as the solar wind , which is a stream of charged particles that emanates from the sun and interacts with the interplanetary medium.
  • The sun also plays a role in the formation and evolution of the solar system, as it was formed from a rotating cloud of gas and dust called the solar nebula, and it will eventually expand into a red giant and engulf some of the inner planets.
