This star is an infra-red source.
From James Kaler's Star Notes:
The Moon and Sun act on the Earth's rotational bulge, and cause the axis to wobble
over a 26,000 year period. The result is that the axis continually moves in a small circle
against the background stars. Polaris is thus only a temporary pole star that will get better
into the 21st century and then will begin to shift away. About the year 1100 BC, the pole
made a reasonably close pass to Kochab, and there are old references to this star being
called "Polaris." Precession also causes the vernal equinox (where we find the Sun on the
first day of spring) to move backwards through the constellations of the zodiac; the
equinox is now in Pisces rather than in Aries where it was when the constellations were
being named. Unlike the Sun, Kochab (which is not particularly unusual among its class),
has run out of internal hydrogen fuel, and is an evolving orange giant star that is now
running for a while on the fusion of helium deep in its core. It is about 50 times bigger
than our Sun. It appears about the same brightness as much more luminous Polaris
because it is much closer and because, at a temperature of 4,000 degrees Kelvin, it
radiates a fair amount of its light in the infrared where we cannot see it. It has a
reputation as a marginal "barium star," the element only a small bit enhanced relative to
what is found in the Sun.
Observations:
C8 at 104x. Star B is very faint, but far from the primary.
