Also how are stars are brighter than others
Principally by size. Larger stars are hotter and brighter. Next by age. As stars get older, they begin to run out of hydrogen fuel, start using helium and swell to red giants. Lastly by composition. Stars that formed earlier tend to have less carbon, oxgyen and "metals" in them.
There are various types of stars, such as main sequence stars (like our sun), red giants, white dwarfs, neutron stars, and black holes. These stars differ in size, mass, temperature, and lifespan. They are classified based on their characteristics and the stage of their evolution.
Red, yellow, and blue stars differ in size and luminosity due to their temperature and age. Red stars are cooler and larger, emitting lower energy light, while blue stars are hotter and smaller, emitting higher energy light. The differences in size and luminosity are also influenced by the stage of the star's life cycle, with younger stars typically burning brighter and hotter.
There are several types of stars based on their size, temperature, and stage of life. Some common types include red giants, white dwarfs, neutron stars, and black holes. These stars differ in characteristics such as mass, brightness, and lifespan.
They are classified as Main Sequence Stars, of which differ in color, size, brightness, and heat. The smallest stars are usually a blueish color and are the hottest, and the largest stars range from yellow to dark red (those being the very biggest). I hope this answered your question. Have a nice day!
The size.
Massive stars are most likely to explode faster than smaller stars.
a galaxy is billions of stars
The colour depicts the temperature.
It doesn't differ from a star, it is a star and it is the second stage in a stars life after the nebula stage.
binary stars are two stars that orbit each other while supernovas and novas stars are stars that explode when it runs out of fuel
Stars vary in characteristics like brightness for example. Stars will also tend to differ in size and color when they are found.
Blue stars are hot, and red stars are cold. You'd think it would be the other way around, but weirdly enough, it's not.
The available ones are above the horizon in a dark sky. The other ones are unavailable.
Yes, Ofcourse stars differ in size. It may be possible that two or more stars have the same size but it is not compulsory for all. As you know sun is also a star. It looks bigger b'coz it is nearer to earth but may be any star exists with same size. but is its age that's differ or what because on the color i got temp. but whats the size bout?
Brightness, Color and mass
every star has different elements in the atmosphere which absorbs the light
