20
times
more

a
binary
star
system,

stars
that

around
their

years,
astronomers
have
discovered
that
Sirius
has
a
disk
of
debris
around
it,
similar
to
the
Kuiper
belt
in
our
own
solar
system.
The
disk
is
believed
to
be
made
up
of
dust
and
other
small
particles
that
were
left
over
from
the
formation
of
the
binary
star
system. Despite
its
dazzling
appearance
in
the
night
sky,
Sirius
has
been
known
to
cause
problems
for
astronomers
trying
to
observe
other
celestial
objects.
Because
Sirius
is
so
bright,
it
can
wash

objects
and
make
them
harder

Sirius
continues
to
fascinate
and
intrigue
astronomers
and
stargazers
alike.
Its
prominence
in
both
