"Star
formation is the process by which dense parts of
molecular clouds collapse into a ball of
plasma to form a
star.
As a branch of
astronomy star formation includes the study of the
interstellar medium and
giant molecular clouds (GMC) as precursors to the star formation
process and the study of
young stellar objects and
planet formation as its immediate products. Star formation
theory, as well as accounting for the formation of a single star,
must also account for the statistics of
binary stars and the
initial mass function.." Source:
Wikipedia Just as the planets orbit around the Sun,
in the same way, Sun orbits around the centre of the Milky Way
galaxy, taking 225,000,000 years to complete a full orbit, traveling
at 800,000 kilometers per hour.
