What else can I help you with?
What are the factors that affect the brightness of stars?
Distance and intervenng or close celestial bodies
What two factor affect a stars apparent brightness?
Two factors that affect a star's apparent brightness are: 1.) The distance between the Earth and the star 2.) The absolute magnitude (the actual brightness) of the star Hope that helps :P
Does age affect the brightness of stars?
Yes, the age of a star can affect its brightness. Younger stars tend to be brighter than older stars because they are still in the process of converting hydrogen into helium through nuclear fusion, which releases a lot of energy. As stars age and exhaust their hydrogen fuel, they can become dimmer.
Do stars have the same brightness and sizes?
No. Stars vary greatly in size and brightness.
Which two groups of stars can have similar brightness?
Variable stars and main sequence stars can have similar brightness. Variable stars, like Cepheid variables, can fluctuate in brightness over time, while main sequence stars maintain a relatively stable brightness due to their fusion processes.
What is a stars brightness known as?
A star's brightness is known as its magnitude. Stars with lower magnitude numbers are brighter than stars with a higher magnitude number.
Temperature and brightness of stars are indicated by what?
Temperature of stars is indicated by their color, with blue stars being hotter than red stars. Brightness of stars is indicated by their luminosity, which is how much light a star emits.
What is the measure of a stars brightness?
Magnitude.
Is shape affects the brightness of the stars?
no
In main-sequence stars how does brightness relate to temperature?
The brightness is very similar to the temperature, the brightness relies on the temperature
What determines how bright stars are?
Size and temperature determine the brightness of stars.
Stars that can change their brightness?
the moon can vary its brightness and the pink elephant called aphadophalis
