Triangulum Galaxy/Stars
The Triangulum galaxy’s diameter is about 60,000 light-years, or about 60% that of our Milky Way. It’s thought to contain some 40 billion stars. In contrast, there are 100-400 billion stars in the Milky Way and a trillion (1,000 billion) stars in the Andromeda galaxy.
What is the smallest galaxy in the universe?

Is segue 2 the smallest galaxy?
Is nebula a galaxy?
A nebula is a cloud of dust and gas, usually tens to hundreds of light years across. A galaxy is much larger — usually thousands to hundreds of thousands of light years across. Nebulae are one of the many things that galaxies are made of, along with stars, black holes, cosmic dust, dark matter and much more.
How big is a nebula?
Nebulae are huge interstellar clouds of gas and dust that range in size from 1 AU to 10 AU, and which are less dense than the deepest vacuum in Earth’s laboratories. Just one portion of of a nebula the size of Earth would weigh only a few kilograms!
