Location of the Solar System
Our solar system is located in the Milky Way galaxy, 19 200 light years away from the centre (as calculated by Jan Oort) on one of the spiral "arms" of the Milky Way. This "arm" is known as the "Orion-Cygnus Arm" or the "Local Spur".
Our solar system orbits around the centre of the Milky Way at approximately 220km/s, completing one orbit about every 250 million years. This is known as the solar system's "galactic year".
Because of our solar system's position on the outer edges of the Milky Way, it has allowed life to evolve on Earth. The intense radiation at the centre of the Milky Way would've negatively impacted our solar system had it been located there. Furthermore, at the centre of the Milky Way, where stars and their systems are crowded closer together, gravitational pulls from the other systems could pull in additional comets from the Oort Cloud causing potentially disastrous collisions with Earth and other planets.
