[53] [54] In absolute terms, M31 is approximately 200,000 light-years in diameter, twice the size of the Milky Way. [54] It is an enormous – 192.4 by 62.2 arcminutes in apparent size [11] – barred spiral galaxy similar in form to the Milky Way and at an approximate magnitude of 3.5, is one of the brightest deep-sky objects in the northern ...

The Sagittarius Dwarf Spheroidal Galaxy (Sgr dSph), also known as the Sagittarius Dwarf Elliptical Galaxy (Sgr dE or Sag DEG), is an elliptical loop-shaped satellite galaxy of the Milky Way. It contains four globular clusters in its main body, [8] with the brightest of them— NGC 6715 (M54)—being known well before the discovery of the galaxy ...
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.
SIMBAD. data. ARICNS. data. HD 140283 (also known as the Methuselah star) is a metal -poor subgiant star about 200 light years away from the Earth in the constellation Libra, near the boundary with Ophiuchus in the Milky Way Galaxy. Its apparent magnitude is 7.205, so it can be seen with binoculars. It is one of the oldest stars known.
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]
