Alpha
Star
of
Capricorn Capricorn
is
a
constellation
that
is
known
for
its
sea
goat
shape,
which
is
a
combination
of
a
goat
and
a
fish.
Within
the
Capricorn
constellation
lies
Alpha
Capricorni,
which
is
the
brightest
star
in
the
constellation.
Alpha
Capricorni
is
also
known
as
Algedi,
which
means
"the
kid"
in
Arabic. Alpha
Capricorni
is
a
double
star
system
composed
of
two
stars
that
orbit
around
a
common
center
of
mass.
The
two
stars
are
separated
by
a
distance
of
about
0.1
arcseconds,
which
is
too
close
to
be
resolved
with
the
naked
eye.
However,
the
two
stars
can
be
seen
separately
with
a
telescope. The
primary
star,
Alpha
Capricorni
A,
is
a
yellow-hued
star
that
is
similar
in
size
and
temperature
to
our
own
Sun.
The
secondary
star,
Alpha
Capricorni
B,
is
a
smaller
and
cooler
red
dwarf
star.
The
two
stars
orbit
each
other
every
20.8
years. In
addition
to
being
a
double
star
system,
Alpha
Capricorni
is
also
a
multiple
star
system.
Alpha
Capricorni
A
has
a
companion
star,
Alpha
Capricorni
C,
that
is
located
about
120
arcseconds
away
from
the
primary
star.
Alpha
Capricorni
C
is
a
blue-white
star
that
is
about
7
times
more
massive
than
our
Sun. Alpha
Capricorni
is
located
about
690
light-years
away
from
Earth.
Despite
its
distance,
it
is
one
of
the
brightest
stars
in
the
night
sky
due
to
its
high
luminosity.
It
has
a
visual
magnitude
of
+4.28,
which
means
that
it
is
visible
to
the
naked
eye

Capricorn
constellation.
As
