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 20,000 light-years (6,100 parsecs) in length. This galactic structure encompasses the Solar System, including Earth. Alternate names include the Local Arm and Orion Bridge, as well as deprecated terms such as the Local Spur and the Orion Spur. It should not be confused with the outer terminus of the Norma Arm, known as the Cygnus Arm.
