Stars
Hey friends, do you know that there are types of stars. Yes, there are some types of stars in space and we are going to find out out about them today. Exciting isn't it? So tell me how many stars are there in the universe? I will tell you the answer at the end.
So there are different kinds of stars. The big ones are even bigger than the sun. Small ones some very odd ones and some new ones. But did you know they are classified into groups? Yes, there is a specific type of star.
1.RED DWARF STARS
They are relatively smaller in size compared to the other stars and therefore they burn at a lower temperature which helps them have a long sustainable life, some say a trillion years. Nearly 70% of the stars in the universe are Red Dwarf stars. But they, since they don't shine so bright it gets difficult for humans to see them with naked eyes.
2.YELLOW STARS
These are medium-sized stars and therefore burn at a medium temperature. There are yellow dwarf stars as well, that are not giants stars. Our sun is one of them. These stars become quite large just before they completely start running out of fuel. The sun too will completely lose its fuel someday but don't worry that won't happen before 5 billion years.
3.BLUE GIANT STARS
As the name suggests, these are big stars and hence burn at a high temperature leaving them with a short lifespan from 10,000-1,00,000 years. Most of the stars you see in the sky are Blue Giant stars. When these stars die, unlike other stars they don't shrink but explode and this type of explosion illuminates the entire sky.
There are all sorts of other stars like giant or supergiant stars which are extremely big, have the shortest life span, and shine the brightest.
FUN FACTS
Every star that you see in the sky is actually bigger than the Sun. Proxima Centauri a red dwarf star is the nearest star to Earth, after the Sun. So remember the question I asked you? how many stars are there in the universe? Astronomers estimate there are about 100 thousand million stars in the Milky Way alone. Outside that, there are millions upon millions of other galaxies also.
