Procyon
Alpha Canis Minoris, 10 Canis Minoris
A very prominent and nearby
star
, Procyon is not only the fifth
brightest
star
in the sky, but is also just eleven
light years
from the
Sun
. The primary
star
is an
F-type
subgiant
, but this has a tiny companion: a
White Dwarf
star
.
Procyon
, easily the
brightest
of the
stars
of
Canis Minor
, lies near the centre of its small home
constellation
.
Possible appearance of
Procyon
: the small but massive
White Dwarf
component draws tendrils of matter from its much larger but less dense
yellow
companion.
