Definition of solar system

The term "solar system" was first coined by the French mathematician and astronomer, Réne Descartes, in the 17th century. Descartes proposed a theory that explained the movement of celestial bodies in the universe, including our own solar system. He suggested that the sun was at the center of our system, orbited by various planets, moons, and comets. The literal meaning of "solar system" is a gravitationally bound collection of celestial bodies, including the sun, that orbit around it. This system is held together by the sun's immense gravitational pull. The essence of this concept was further elaborated and refined by the famous astronomer, Johannes Kepler, who studied the motions of the planets in our solar system and discovered various laws that govern their movements. The term "solar system" has since become a ubiquitous term in astronomy and astronautics, and it serves as a handy way to refer to the collection of celestial objects in our own backyard. This concept has also helped us better understand our place in the vastness of the universe and has led to numerous discoveries and innovations in space exploration.
