How many stars are there? Do they all have names? How often does a star fall? And what happens to the stars after they have fallen?

Just in our Galaxy (the Milky Way), there may be as many as 400 thousand million.
400,000,000,000
(100 for each person on Earth)

Less than 200 stars have a proper name.

Most visible stars have a Bayer designation (a greek letter followed by the latin name of the constellation) or a Flamsteed designation (name of the constellation + a number).

There are many other systems to name stars (but they are not really names, in the same way that a Social Security Number may identify a person, but it is not the person's name)

More than all the grains of sand on the earth. Not all stars have names, most have a reference number, for there are so many stars. Stars do not fall, what people call falling stars are small meteorites which burn up as they enter the earths atmosphere, because they are travelling so fast, tens of thousands of miles per hour the friction with air particles in the upper atmosphere heat them to such a high temperature they burn up and produce a bright white light.

Each star is a sun, and we designate classes between suns. Our sun is a 'normal' size, you can have suns that are hundreds of times bigger and more powerful. There are millions of suns in our galaxy alone.

Some stars do have names, but there's just too many to count. The closest star to the planet is Alpha Centuria (if you count out our own sun).

Stars in the sky are not to be confused with asteroids. When a star 'falls' it's a piece of rock that is travelling the speed of a bullet across the solar system. When you see the stars in the sky, they are fireballs somewhere thousands of light years away, just sitting there, well, burning.

there are about 10^22 stars in the universe. Several thousand are visible from Earth.
Stars don't fall. A 'shooting star' is a micro-meteoriod (dust particle) burning up upon entry of Earth's atmosphere. Earth gained about 50 tons of 'stardust' each day.

There are an infinite number of stars (too many to accurately count), and because there are so any not all of them have names, most have numbers. Star do not "fall", when one refers to a falling star, they are actually referring to meteorites that graze the atmosphere and ignite from the friction, they are also refered to as shooting stars.

More stars than all the grains of sand on Earth. All stars eventually die, but new stars are continually being born.
Many stars are named but not all of course.

There are 70 thousand million million million stars in the Universe, dispersed across 100 thousand million different Galaxies. The Earth is in one of those Galaxies!

Stars "fall" quite often. Apparently, if you look at the sky for long enough, you will see lots of shooting stars. Where one leaves a space, another one appears to take its place. The stars burn themselves out ... and just disappear, but I guess you could say they've run out of energy (gases).

The marvel of space ... doesn't it make you feel small and glad to be alive?

Stars do not fall

There are billions of gallaxies and these gaxaxies have a trillion stars each.
