the

It
has
also
been
known
as
Graffias,
a
name
derived
from
Greek
mythology,
where
it
was
believed
to
represent
one
of
the
scorpion's
claws. Acrab
is
a
binary
star
system,
meaning
it
consists
of
two
stars
orbiting
around
a
common
center
of
mass.
The
two
stars
are
very
close
to
each
other
and
cannot
be
seen
separately
with
the
naked
eye.
They
orbit
each
other
every
10.5
days. The
star
system
is
located
at
a
distance
of
about
520
light-years
from
Earth.
It
has
a
mass
18
times
that
of
the
Sun
and
is
about
1,200
times
brighter.
It
radiates
a
blue-white
color
and
is
classified
as
a
rare
B0
Ve
main
sequence
star. Despite
its
brightness,
Acrab
is
surrounded
by
a
cloud
of
dust
and
gas
that
makes
it
difficult
to
study.
The
cloud,
called
a
circumstellar
envelope,
absorbs
some
of
the
star's
light
and
makes
it
appear
dimmer. The
star's
mysterious
and
alluring
qualities
have
led
to
its
prominence
in
astrological
and
mythological
traditions.
In
ancient
Greek
mythology,
Scorpius
was
associated
with
the
story
of
Orion,
a
great
hunter
who
was
killed
by
the
scorpion
sent
by
Gaia,
the
earth
goddess.
In
astrology,
Scorpio
is
associated
with
qualities
such
as
passion,
loyalty,
and
intensity. Overall,
Acrab
is
a
fascinating
star
that
continues
to
intrigue
astronomers
and
stargazers
alike.
Its
brightness
and
location
in
the
constellation
Scorpius
make
it
a
prominent
feature
of
the
night
sky,
while
its
binary
nature
and
circumstellar
envelope
add
to
its
mystery
and
allure.
