PegasusPegasus
Particulars:
General:
One of the large constellations of the northern hemisphere. It
is thought to represent a winged horse. The Four of the stars alpha
Peg, beta Peg, gamma Peg and alpha And
form an easy to view square. Originally the fourth star was
called delta Peg, but nowadays this star is assigned to
the neighbouring constellation Andromeda.
Stars and other objects
The brightness of the red giant star beta,Peg, called Scheat
(the shoulder), varies irregularly between 2nd and 3rd magnitude.
The double epsilon Peg, called Enif, is a
wide pair, very unequal in brightness. The first component is a
K2 super giant of 2.39 mag. The second component of 9th mag
becomes visible in binoculars or small scopes.
1 Peg is also an object for small scopes. The pair
consists of a 4.13 mag F5 subgiant with an 9th mag companion.
The 6th mag globular cluster M15 is one of the densest of
this type. It is notable for its collapsed core as well as for
its high amount of known variable stars and pulsars. To view it
binoculars and small scopes are sufficient. The cluster appears
as a misty patch. To resolve individual stars larger telescopes
are required (with an aperture of 150 mm at least). Detailed
information can be found in the Messier database.
Two meteor showers are associated with this constellation: The Alpha
Pegasids were discovered 1959. The duration seems to be from
29th of October to 12th of November.
The Upsilon Pegasids are active from 25th of July to 19th
of August with the maximum occurring on August, 8th.
