M33 = NGC598 ( 1h 33.9m +30°39´, 5.7 mag. )
Pinwheel Galaxy was discovered by Messier on Aug. 25, 1764.
M33
The Pinwheel Galaxy, the third largest member of the Local Group, after Andromeda and the Milky Way. It is a spiral galaxy that lies 2.6 million light-years away.

M33, the Triangulum galaxy, is like a miniature version of the Milky Way. It has a big bulge of stars in the center surrounded by bright spiral arms, dark dust lanes, and bright knots where new stars are being born.

M33 is a Hubble type Sc galaxy; it is smaller and fainter than the other two spirals, being only about as bright visually as a few billion suns.
"M33 is a gigantic laboratory where you can watch dust being created in novae and supernovae, being distributed in the winds of giant stars, and being reborn in new stars," added University of Minnesota researcher and lead author Elisha Polomski.
The other galaxy (M33 in Triangulum) is much harder to see although it is at a similar distance to the Andromeda galaxy. This is because it is smaller and less bright intrinsically. It too is a spiral galaxy.

Distinct structure was reported by William Parsons, 3rd Earl of Rosse, whose 72-inch speculum-metal reflector showed clear spiral features in some bright nebulae such as M33, M51, and M101.
The spiral galaxy M33 is a member of our Local Group of galaxies. After our own galaxy and the Andromeda Galaxy, M31 it is the third largest in the Local Group. Before trying to locate fainter objects, viewing M33 is a good test.
In 1924 Edwin Hubble detected Cepheids in the Andromeda nebula, M31 and the Triangulum nebula M33. Using these he determined that their distances were 900,000 and 850,000 light years respectively.
Three of them (the Milky Way, Andromeda, and M33) are spirals; the remainder are dwarf irregular and ellipticals. Together, these galaxies form the Local Group"a new level of structure in the universe above the scale of our Galaxy.
Located in the constellation Triangulum, M33 is a member of our local group of galaxies. It is a spiral galaxy with a diameter of 60,000 light-years, which makes it much smaller than its neighbor, M31.
This contains around 70 galaxies with the big ones being our own Milky Way, the Andromeda Galaxy (M31), and the Triangulum Galaxy (M33).

It is a group of about 30 that is about 5 million across. The largest of the galaxies are , Triangulum, and our . The Local Group also includes Fornax, the Large and Small Magellanic Clouds, M32, M33, M101, and 9 dwarf spheroidal galaxies.
A possible cause of such a warp could be gravitational interaction with the satellite galaxies near M31. The galaxy M33 could be responsible for some warp in M31's arms, though more precise distances and radial velocities are required.
The best fit to these data for clouds with masses between 105 and 2 x 106 Msun yields a constant of proportionality of 3.0 x 1020 H2 cm-2 (K km s-1)-1. The similarity of the clouds in other galaxies (M31, M33, and IC 10) to the Milky Way justifies ...
The other spiral galaxy in the Local Group is the Triangulum Galaxy (M33), which is 900 kpc away. The distances of other members of the Local Group are typically around 750 kpc, although several are farther than 1.5 Mpc away.
The Milky Way is between the ``b'' and ``c'' groups with a bar, so it is an SBbc-type spiral galaxy. Most spirals are luminous. Some other examples of spiral galaxies are M31 (the Andromeda Galaxy) and M33 (a small spiral in the Local Group).
Past this star half as far is M33. Four stars in the shape of a "kite" should be visible in the telescope. The galaxy will look like a large, but very faint patch of light in this kite. Be sure to use your lowest power.
According to Hyginus, some people also saw it as the island of Sicily, which was originally known as Trinacria on account of its three promontories. Trinacria was the home of Ceres, goddess of agriculture. Triangulum contains M33, ...
of the other galaxies in our Local Group are gravitationally bound either to the Andromeda Galaxy or to our Milky Way Galaxy. Inside of our local group but outside of our Galaxy are objects 4,000,000 LY to 1,000,000 LY from the Sun: M31, M32, M33.
This is because of interactions with M33, a face on spiral galaxy not far from M31. Eventually all three galaxies will form one giant elliptical galaxy, rushing to take its place in the Virgo Supercluster.
