Key Points

• The Milky Way is the galaxy that contains our Solar System.
• It is a barred spiral galaxy with a diameter of about 100,000 light-years.
• The Milky Way is estimated to contain 100-400 billion stars, including our Sun.
• It is part of the Local Group of galaxies, which also includes the Andromeda Galaxy.
• Our Solar System is located in the Orion Arm of the Milky Way, about 27,000 light-years from the Galactic Center.

Additional Information

• Galactic Center: The rotational center of the Milky Way, containing a supermassive black hole named Sagittarius A*.
• Spiral Arms: The Milky Way has several spiral arms, including the Perseus Arm, the Carina-Sagittarius Arm, and the Orion Arm where our Solar System resides.
• Local Group: A galaxy cluster that includes the Milky Way, Andromeda, Triangulum, and about 54 other galaxies.
• Dark Matter: The Milky Way, like other galaxies, contains a significant amount of dark matter, which affects its rotation and structure but does not emit light.
• Galactic Halo: A roughly spherical region surrounding the Milky Way, containing old stars, globular clusters, and dark matter.
