What type of galaxy is the M33?
Spiral galaxy
Spiral galaxy M33 is located in the triangle-shaped constellation Triangulum, earning it the nickname the Triangulum galaxy. About half the size of our Milky Way galaxy, M33 is the third-largest member of our Local Group of galaxies following the Andromeda galaxy (M31) and the Milky Way.
How big is the Triangulum Galaxy in the sky?
about 60,000 light-years
Properties. With a diameter of about 60,000 light-years, the Triangulum Galaxy is the third largest member of the Local Group of galaxies, roughly 60% the size of the Milky Way. It may be a gravitationally bound companion of the Andromeda Galaxy.
Is M33 visible to naked eye?
M33 The Triangulum Galaxy. Lying at a distance of 2.7 million light years, this large face-on spiral galaxy is certainly visible in binoculars, but is said to be visible with the naked eye. With a published magnitude of +5.7, it certainly seems to come above the usually accepted naked eye magnitude of +6.0.
How far is M33 in light-years?

What does M33 mean?
Filters. (astronomy) The Triangulum Galaxy; a spiral galaxy in the Local Group, together with the Milky Way galaxy. It is at a distance of approximately 2.6 million light years from Earth, in the direction of the constellation Triangulum.
Is Triangulum a dwarf galaxy?
Triangulum II (Tri II or Laevens 2) is a dwarf galaxy close to the Milky Way Galaxy. Like other dwarf spheroidal galaxies, its stellar population is very old: the galaxy was quenched before 11.5 billion years ago. It contains only 1000 stars, yet is quite massive, having a solar mass to light ratio of 3600.
Does M33 have a black hole?
Unlike many other large galaxies, such as the Milky Way and Andromeda, M33 does not have a supermassive black hole in its center.
Can you see M33 with binoculars?
M33 is easily seen in modest binoculars from a dark site but it’s really quite a different object if seen in a larger telescope as there are several bright nebulae that can be seen.
Is the Triangulum Galaxy a spiral galaxy?
The Triangulum galaxy is about 2.7 million light-years from our Milky Way. It’s a spiral galaxy, whose face-on orientation has given it the nickname Pinwheel Galaxy (another face-on spiral, Messier 101, also has this nickname). The Triangulum galaxy is the 3rd-largest member of our Local Group of galaxies.
How big is M33?
About half the size of our Milky Way galaxy, M33 is the third-largest member of our Local Group of galaxies following the Andromeda galaxy (M31) and the Milky Way. Comprised of 54 separate Hubble fields of view, this image is the largest high-resolution mosaic of M33 assembled to date by any observatory.
Is the Triangulum Galaxy dimmer than M33?
Despite it’s size, the Triangulum Galaxy appears much dimmer than M31 – The Andromeda galaxy. If you are new to astrophotography, chances are that the Triangulum Galaxy is one of the first few galaxy names you have learned. I have managed to image the M33 Galaxy from my backyard for multiple nights over the course of nearly a week.
Who was the first to catalog the Galaxy M33?
Although others may have viewed the galaxy earlier, Charles Messier was the first to catalog M33 after observing it in August 1764.
What do we know about star formation in M33?
Blue-colored regions scattered throughout the image reveal numerous sites of rapid star birth in M33. In fact, Hubble’s observations reveal that the Triangulum galaxy’s star formation rate is ten times higher than the average found in the Andromeda galaxy, previously surveyed by Hubble in similar detail.
