* Defining "medium" is arbitrary: There isn't a universally agreed upon cutoff for what constitutes a "medium" mass star.
* We don't know the exact number of stars: Our ability to observe and categorize stars is limited by the vastness of space and the limitations of our telescopes. We can only see a portion of the stars in our galaxy, let alone the rest of the universe.
However, we can provide general estimations based on what we know about star formation and stellar evolution:
* Low-mass stars (less than 0.8 solar masses): These are the most common type of star. Estimates suggest they make up roughly 85% to 90% of the stars in the Milky Way galaxy.
* Medium-mass stars (0.8 to 8 solar masses): These stars are less common than low-mass stars, but still represent a significant percentage of the galactic population. They likely comprise 10% to 15% of the stars.
* High-mass stars (more than 8 solar masses): These are the rarest type of star. They are thought to account for only less than 1% of the stars in the Milky Way.
Important Notes:
* These percentages are rough estimates, and the actual proportions could vary slightly.
* The distribution of stars might not be uniform throughout the galaxy or across different galaxies.
