A star is an astronomical
object comprising a luminous spheroid of plasma held
together by self-gravity.
The nearest
star to Earth is
the Sun. Many other stars are
visible to the naked eye at night, but their
immense distances from Earth make them appear as fixed points
of light. The most prominent stars have been categorised
into constellations and asterisms,
and many of the brightest stars have proper
names. Astronomers have
assembled star
catalogues that identify the known stars and provide
standardized stellar
designations. The observable
universe contains an estimated 1022 to 1024 stars. Only about 4,000 of
these stars are visible to the naked eye,[1] all
within the Milky
Way galaxy.
