I am writing the answer which I am
extending to explain you a bit more on
Stars are made of very hot gas. We can
say that they are big exploding balls of mostly
hydrogen and helium, which are the two lightest
elements. Stars shine by burning hydrogen into
helium in their cores, and later in their lives
create heavier elements. Most stars have small
amounts of heavier elements like carbon, nitrogen,
oxygen and iron, which were created by stars that
existed before them. After a star runs out of
fuel, it ejects much of its material back into
space. New stars are formed from this material. So
the material in stars is recycled.
nearest star, the Sun, is so hot that the huge
amount of hydrogen is undergoing a constant
star-wide nuclear reaction, like in a hydrogen
bomb. Even though it is constantly exploding in a
nuclear reaction, the Sun and other stars are so
large and have so much matter in them that it will
take billions of years for the explosion to use
all the "fuel" in the star.
We can not
rearrange the stars. There are tremendously big
forces from the universe that put the stars in the
places where they are located.
