The Milky Way is the galaxy[nb 1] that contains our Solar System.
The Milky Way is a barred spiral galaxy with a diameter between 100,000[26] and 180,000 light-years (ly).[27] It is estimated to contain 100–400 billion stars.[28][29] There are probably at least 100 billion planets in the Milky Way.[30][31] The Solar System is located within the disk, about 26,000 light-years from the Galactic Center, on the inner edge of the Orion Arm, one of the spiral-shaped concentrations of gas and dust. The stars in the innermost 10,000 light-years form a bulge and one or more bars that radiate from the bulge. The galactic center is an intense radio source known as Sagittarius A*, likely a supermassive black hole.
Stars and gases at a wide range of distances from the Galactic Center orbit at approximately 220 kilometers per second. The constant rotation speed contradicts the laws of Keplerian dynamics and suggests that much of the mass of the Milky Way does not emit or absorb electromagnetic radiation. This mass has been termed "dark matter".[32] The rotational period is about 240 million years at the position of the Sun.[18] The Milky Way as a whole is moving at a velocity of approximately 600 km per second with respect to extragalactic frames of reference. The oldest stars in the Milky Way are nearly as old as the Universe itself and thus probably formed shortly after the Dark Ages of the Big Bang.[9]
The Milky Way has several satellite galaxies and is part of the Local Group of galaxies, which form part of the Virgo Supercluster, which is itself a component of the Laniakea Supercluster.[33][34]

The Laniakea Supercluster (Laniakea; also called Local Supercluster or Local SCl or sometimes Lenakaeia)[2] is the galaxy supercluster that is home to the Milky Way and approximately 100,000 other nearby galaxies.[3]
Oh just fuck off.
You're twisting my melon, man!
