The Solar System is the Sun and everything gravitationally bound to it — eight planets, dwarf planets, moons, asteroids, comets, and distant icy reservoirs — formed about 4.568 billion years ago and located in the Milky Way’s Orion–Cygnus arm. (If you’re in Dhaka today, these objects are the same; their visibility from Earth depends on date and time.) NASA Solar System Exploration Wikipedia
