Messier 15, ein bekannter 6,2 mag heller Kugelsternhaufen im Sternbild Pegasus.
Seine Flächenausdehnung beträgt 18 Bogenminuten. Sein wahrer Durchmesser ist
175 Lichtjahre in einer Entfernung von 33600 Lichtjahren. Er ist einer der dichtesten
Kugelsternhaufen unserer Galaxis. Konzentration Klasse IV.
Er besteht aus mehreren hunderttausend Sternen.
Bei M 15 wurde im Jahre 1928 der erste von bisher drei Planetarische Nebel in einem
Kugelsternhaufen entdeckt. PK 065.0-27.3 mit 14,9 mag nahe dem Zentrum des
Haufens. Bisher wurde auch 112 Variable Sterne sowie 8 Pulsare gefunden.
Man nimmt an das sich im Zentrum von M 15 ein schwarzes Loch befindet.

Messier 15, a known 6.2 mag bright globular cluster in the constellation Pegasus.
Its surface area is 18 minutes of arc. Its true diameter is
175 light-years at a distance of 33,600 light-years. He is one of the densest
Globular star cluster of our galaxy. Concentration class IV.
It consists of several hundred thousand stars.
At M 15 in 1928 the first of so far three Planetary Nebulae in one
Globular cluster discovered. PK 065.0-27.3 with 14.9 mag near the center.
So far also 112 variable stars as well as 8 pulsars were found.
It is assumed that there is a black hole in the center of M 15.
