Triangulum Galaxy is a spiral galaxy approximately 3 million
light-years (ly) from Earth in the constellation Triangulum. It is
catalogued as Messier 33 or NGC 598, and is sometimes informally
referred to as the Pinwheel Galaxy, a nickname it shares with
Messier 101. The Triangulum Galaxy is the third-largest member of
the Local Group of galaxies, which includes the Milky Way, the
Andromeda Galaxy and about 44 other smaller galaxies. It is one of
the most distant permanent objects that can be viewed with the naked
eye.
The galaxy is the smallest spiral galaxy in the Local Group and it
is believed to be a satellite of the Andromeda Galaxy due to their
interactions, velocities and proximity to one another in the night
sky.
Under exceptionally good viewing conditions with no light pollution,
the Triangulum Galaxy can be seen with the naked eye. It is one of
the most distant permanent objects that can be viewed without the
aid of a telescope. Being a diffuse object, its visibility is
strongly affected by small amounts of light pollution. It ranges
from easily visible by direct vision in dark skies to a difficult
averted vision object in rural or suburban skies. For this reason,
Triangulum is one of the critical sky marks of the Bortle Dark-Sky
Scale. |
