Question

Why can’t some stars e seen with the naked eye??

Answer 1

Answer:

Because they are point sized sources andsome stars even dont twinkle so are dim and we cant see

Answer 2

Hey...!!

• Many are just too dim. It is estimated that 80% of all stars in our galaxy are stellar class M (red) dwarves, yet not a single one is visible to the unaided eye. So now we've reduced the pool of visible stars by 80%.

• Even if huge and bright, they are simply too far away. Our galaxy is about 130,000 light years across. We're about 30,000 light years from the galactic center. Now, I don't have my charts in front of me, but I believe the most distant star we can see unaided is about 4000 light years distant in the constellation Cassiopeia.

• Along with distance, the majority of stars are blocked from our sight due to the galactic arm and dust lanes of sagitarrius arm of the milky way galaxy. This eliminates over half the galaxy.

• If you consider approximately 3,000 stars are visible to the unaided eye under the very best of seeing conditions, and there is an estimated 250 billion stars (+/— 150 billion), what we can see is a very minute fraction.
