 | | Stars are almost always found in collections called galaxies, together with gas, dust, and "dark matter"; ~10-20% of a galaxy is composed of stars, gas, and dust. |
 | | Galaxies are held together by gravitational attraction and the galactic components orbit a common centre. |
 | | Our own galaxy, the Milky Way, sometimes simply called the Galaxy (with uppercase), is a large barred spiral galaxy about 30 kiloparsecs or 100,000 light years in diameter and 3,000 light years in width, contains about 300 billion stars and has a total mass of about a trillion times the mass of the Sun. |
