In

the brightest

constellation

Orion

are

bright stars

, as blue

-

white

Rigel

and

a

golden

orange

(pictured

below

)

,

but none

surpasses

Sirius

.

is a

blue star

,

which is part of

the constellation

Orion

, located in the

bottom right of the

unter.

Slightly

lower

in

brightness

than

Capella

,

Rigel

is a classic example

of a

blue

giant

,

very

hot,

blue,

and

bright

.

Rigel

was once

considered to be

brighter than

any of the

other giants

that populate the

Orion

region

.

Now

we think that

is a little

closer to us

, about

800

light-years away

,

than previously estimated

.

So maybe

Rigel

is just one of

the brightest

stars in

the

winter

sky

.

Even so

,

its

brightness

is

thousands of

times greater

than that of

our sun

.
