    en.wikipedia.org/wiki/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. [2] This galactic structure encompasses the Solar System, including Earth.

    The Milky Way [c] is the galaxy that includes the Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars in other arms of the galaxy, which are so far away that they cannot be individually distinguished by the naked eye.

  4. Scutum–Centaurus Arm - Wikipedia

    en.wikipedia.org/wiki/Scutum–Centaurus_Arm

    The Scutum–Centaurus Arm, also known as Scutum-Crux arm, is a long, diffuse curving streamer of stars, gas and dust that spirals outward from the proximate end of the Milky Way's central bar. The Milky Way has been posited since the 1950s to have four spiral arms ; numerous studies contest or nuance this number. [ 1 ]

    Observed structure of the Milky Way's spiral arms. The Carina–Sagittarius Arm (also known as the Sagittarius Arm or Sagittarius–Carina Arm, labeled -I [clarification needed]) is generally thought to be a minor spiral arm of the Milky Way galaxy. [1] Each spiral arm is a long, diffuse curving streamer of stars that radiates from the Galactic ...

    The outer end of it is identified either with the Cygnus Arm (not to be confused with local and minor Orion-Cygnus Arm), which lies outside the Perseus Arm, or the Outer Arm, which is located farther away from the center of the Galaxy than the Cygnus Arm. [1] The Norma Arm begins 2.2 kpc from the Galactic Center, [2] and extends outward to a ...

    en.wikipedia.org/wiki/Perseus_Arm

    The Milky Way is a barred spiral galaxy with two major arms and a number of minor arms or spurs. [1] The Perseus Spiral Arm, with a radius of approximately 10.7 kiloparsecs, is located between the minor Cygnus and Carina–Sagittarius Arms. [1] It is named after the Perseus constellation in the direction of which it is seen from Earth.
