The Mind Blowing Scale of Galaxies: Exploring the Universes Vastness



As of my last update in September 2021, the Milky Way is a barred spiral galaxy, and its scale can be described in terms of its size and mass:

Size: The Milky Way has an estimated diameter of about 100,000 to 180,000 light-years. A light-year is the distance that light travels in one year, approximately 9.46 trillion kilometers (5.88 trillion miles). This means the Milky Way is immense, spanning a vast region of space.

Mass: The total mass of the Milky Way is estimated to be about 100 to 400 billion times the mass of our Sun. This calculation is based on the gravitational influence it has on nearby galaxies and other astronomical observations.

It’s important to note that these values are only approximations, and new discoveries and observations may refine our understanding of the Milky Way’s size and mass in the future. Additionally, my information might be outdated, and I recommend checking more recent astronomical sources for the latest data on the scale of the Milky Way galaxy.
