Hard to explain. Usually stars get bigger if they grow. Very large stars have shorter life. A very big star can end it's life as a super nova or a black hole.
Stars can be classified into different sizes based on their mass and luminosity. The most common sizes are dwarf stars (like our Sun), giant stars (larger and more luminous than the Sun), and supergiant stars (the largest and most luminous stars, like Betelgeuse and Rigel). There are also intermediate sizes like subgiant stars.
like people, no 2 stars are absolutely identical so yes
Stars are celestial bodies made of gases that emit light and heat. They are often visible in the night sky and have different colors and sizes based on their temperature and age. In human culture, stars can symbolize hope, guidance, and inspiration.
because they are different sizes and different distances away from earth
It varies. Stars can be all different sizes!
No, stars come in many different sizes, masses and densities. Further, a star will change its size over its lifespan.
No.., the sun is a ball of gas, and stars are balls of gas.. so basically yeah - but but that means all stars are twins at different sizes.
No, not really. The Big Bang theory has to do with the universe as a whole, not piddly little things like stars.
because the sizes and the distances away from earth are different
They are all three. That is why some stars are called White Dwarfs (they are relatively small) and Red Giants or even Supergiants. The Sun is a middle-sized star.
Our own galaxy, the Milky Way consists of about 200 billion stars.
Roughly around 400g but different sizes mean different weights.
