Cluster population: 3,000
Magnitude: 1.2
Notes:
Known since Biblical times, Messier added it to his catalog on March 4, 1769, and
was the last entry to his original list.
It is 78 million years old and 7 light years in diameter. It is about 3 times as far as the
Hyades and is moving through space at about 25 miles per second. (At that hectic clip, it
will take 30,000 years to move a distance equal to the apparent diameter of the moon.)
Alcyone is 1,000 times as bright as the Sun and probably 10 times its size. The
faintest stars in the cluster are 1% as bright as the Sun (red dwarfs).
All the major stars rotate rapidly, with Pleione rotating 100 times faster than the Sun.
Pleione is also slightly variable and has a violently turbulent atmosphere (of course, with
an egg beater that large and fast under it, you can see why), showing at times a shell in
the spectrum, at other times no shell. Pleione is about 5 times as large as the Sun, so its
rapid rotation is even more remarkable, and probably produces a very flattened discus
shape.
There are no red giants yet, the H-R diagram showing a classical stable Main
Sequence pattern. In fact, much of the nebular incubator that hatched these stars is still
there, having not yet been totally dispersed by the fierce stellar winds of the B giants.
(You can glimpse this nebulosity around Merope on good nights.)

Since the Pleiades lie near the ecliptic, they are often occulted by the Moon. Such an
event is a special treat, especially when the dark limb of the Moon takes its leisurely
stroll through the cluster, clipping out the stellar beacons one by one in what is probably
one of the most instantaneous events your eye can record.
In 1999, David J. Pinfield of The Queen's University in Belfast, Northern Ireland,
completed a mass study of the Pleiades and concluded that the total cluster mass, matter
both visible and unseen, is about 735 solar masses.
Observations:
C8 at 10x. It looks best in the spotter. Steve Coe has a colorful and poetic description
for this cluster: "Glittering blue-white diamonds shining through lace."

Its diameter would be 3,460 miles. The stars would be 120 miles apart

Notes:
The most conspicuous of the Pleiades reflection nebulae is NGC 1435 around
Merope, also called "Tempel's Nebula", as it was discovered by Wilhelm Tempel on
October 19, 1859. This is the only one of the reflection nebulae in the Pleiades which was
known to John Herschel when he compiled his General Catalog (GC) in 1864, and has
been assigned the number GC 768. In the NGC, it is described as very faint, very large,
diffuse nebula around Merope; its angular diameter is given as half a degree (same as the
Full Moon).
The Merope Nebula contains a bright knot, IC 349, which is very small and 36" south
following (east) of Merope (more exactly, at position angle 165 deg). This small

Zone 133
reflection nebula was first discovered by E.E. Barnard in 1890. It appears such bright,
compared to its suroundings, because of its proximity to the star Merope.
