According to legend, when Tama-rereti took his canoe out onto a lake, he found himself far from home as night was falling.
Orion Arm. The Orion Arm, also known as the Orion–Cygnus Arm, is a minor spiral arm within the Milky Way Galaxy spanning 3,500 light-years (1,100 parsecs) in width and extending roughly 10,000 light-years (3,100 parsecs) in length. [2] This galactic structure encompasses the Solar System, including Earth.
Its speed around the center of the Milky Way is about 220 km/s, so that it completes one revolution every 240 million years. This revolution is known as the Solar System's galactic year . [262] The solar apex , the direction of the Sun's path through interstellar space, is near the constellation Hercules in the direction of the current location ...
The Milky Way started out small and grew in size as it merged with other galaxies, gaining stars as well as hydrogen to form more stars. Each galaxy has hydrogen gas that aids in the birth of stars.

The Solar System travels alone through the Milky Way in a circular orbit approximately 30,000 light years from the Galactic Center. Its speed is about 220 km/s. Its speed is about 220 km/s. The period required for the Solar System to complete one revolution around the Galactic Center, the galactic year , is in the range of 220–250 million years.
