A
more technical description of a star is “a
self-luminous celestial body consisting of a mass
of gas held together by its own gravity in which
the energy generated by nuclear reactions in the
interior is balanced by the outflow of energy to
the surface, and the inward-directed gravitational
forces are balanced by the outward-directed gas
and radiation pressures.”

Stars
have a life of their own. They each eventually
fade and die. We think of them as permanent because this happens over a
very long time span compared to our existence on
earth.

While
approximately one millions Earths could fit into
the central star of our solar system, the Sun,
more than a million Suns could easily fit within
the space of other larger stars.
That means that one trillion Earths could
fit into a large star!
