Which stars have the lowest absolute brightness? Supergiants Giants Yellow stars Dwarfs

To understand which type of stars have the lowest absolute brightness, we should first review the definitions of the different categories of stars mentioned:

1. Supergiants: These are some of the largest stars in the universe, known for their immense size and high absolute brightness. They are among the brightest stars visible in the night sky.

2. Giants: These stars are also quite luminous but are smaller than supergiants. They are still brighter than many other types of stars.

3. Yellow stars: Typically, this refers to stars like the Sun (G-type stars), which have moderate absolute brightness compared to others.

4. Dwarfs: These stars, particularly red dwarfs, are smaller and less luminous than the other types mentioned. They have the lowest absolute brightness of all star categories.

Based on this classification, the stars with the lowest absolute brightness are Dwarfs, particularly red dwarfs, which possess much lower luminosity than supergiants, giants, or yellow stars.
