Question

stars in the sky can appear brighter or dimmer than each other based on the stars luminosity and from the earth. a stars is how bright the star appears from earth, while a stars is the actual brightness of a star, also called luminosity.

h - r diagrams demonstrate the relationship between a stars absolute magnitude/luminosity and . for main sequence stars, as the stars temperature increases so does its absolute

distance surface temperature
diameter shape
apparent magnitude
available magnitude
luminosity magnitude
absolute magnitude

Explanation:

• The first blank: The brightness of a star as seen from Earth is affected by its distance. So, "distance" fits.
• The second blank: "Apparent magnitude" is the term for how bright a star appears from Earth.
• The third blank: "Absolute magnitude" is the actual brightness (luminosity) of a star.
• The fourth blank: H - R diagrams show the relationship between absolute magnitude/luminosity and "surface temperature".

Answer:

1. distance
2. apparent magnitude
3. absolute magnitude
4. surface temperature
