Primarily in mass. Smaller stars are smaller and dimmer, and live longer; more massive stars are bigger, LOTS brighter, and die sooner. A small star - or even an average star like our Sun - will last for billions of years. A giant star like Betelgeuse or Sirius will go supernova and blow itself apart in only a few million years.
I guess you mean "our Sun". It is in no way unique - there are both larger and smaller stars for example. The only important thing about itb - at least for us - is that it is OUR Sun.
Main sequence stars are found in all galaxies.
Giant stars differ from main sequence stars primarily in size, luminosity, and temperature. While main sequence stars fuse hydrogen into helium in their cores, giants have exhausted their hydrogen and are now fusing heavier elements, leading to increased brightness and larger radii. Additionally, giant stars often have cooler surface temperatures compared to main sequence stars of similar mass due to their expanded size. This results in a distinct position on the Hertzsprung-Russell diagram, where giants occupy the upper regions compared to the more centralized position of main sequence stars.
Stars are classified by the H-R scale. They are classified by their luminosity and their temperature. They can also be classified by stage; our sun is a main sequence star while the center of the milky way is a black hole(the corpse of a super massive star).
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.
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.
sun doesn't preform binary systems.binary systems: are when one or more stars rotates around the sun. which our most common stars have done, except the sun.
The size.
Stars differ in size, temperature, color, and mass. These differences dictate their brightness, lifespan, and the elements they produce through nuclear fusion reactions. Additionally, stars can vary in age, composition, and evolutionary stage, leading to a diverse range of stellar phenomena in the universe.
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 smallest stars in the main sequence are the stars with cooler surface temperatures.
A white main sequence star has the hottest core.
