The Milky Way Galaxy is our home in the vast universe. It is a barred spiral galaxy that contains over 100 billion stars, including our own Sun. Spanning more than 100,000 light-years in diameter, the Milky Way hosts countless solar systems, nebulae, star clusters, and possibly billions of habitable planets.
Located in the Local Group of galaxies, the Milky Way is gradually moving toward the Andromeda Galaxy, with which it may collide in about 4 billion years. Milkyway galaxy has a supermassive black hole at its center, known as Sagittarius A*, which influences the orbits of nearby stars.
