A
solar mass
(often denoted
as
\(
M
_\odot \)) is
a
standard unit of
mass
used in
astronomy
to
measure
the
mass
of
stars
and other
astronomical objects
. It is defined
as
the
mass
of the
Sun
, which is approximately \(
1
.989 \
times
10
^{30} \)
kilograms
(or about \( 333,000 \)
times
the
mass
of
Earth)
.
