What does the size of a galaxy mean?
The size of a galaxy refers to its physical dimensions, typically measured in terms of its diameter or radius. Larger galaxies can contain billions to trillions of stars, while smaller galaxies may have fewer stars. Galaxy size can also provide clues about its age, structure, and evolutionary history.
Do stars have the same brightness and sizes?
No. Stars vary greatly in size and brightness.
Why a stars color and brightness is important?
A star's color tells us it's temperature, and indirectly, can tell us a lot about it's size. It's absolute brightness (as opposed to it's apparent brightness) also helps us define the star.
If we could see unaided the entire disk of the Andromeda Galaxy with the same brightness as its center would the moon be large enough to totally eclipse it?
No. The dimensions of the Andromeda Galaxy are about 190 minutes x 60 minutes (3 degrees+10 minutes x 1 degree) , which is far larger than the Moon's apparent size of 30 minutes (1/2 degree)

How much larger is the Andromeda galaxy than earth?
One can not realistically measure the size of a galaxy in terms of the size of the Earth. One usually measures the size of a galaxy in terms of light years. The solar system of which the Earth is just a small speck sits in our local galaxy, the Milky Way which is 100,000 to 120,000 light years across, while the Andromeda galaxy is slightly larger at 220,000 light years in diameter.
What is the rank of India in terms of size in world?
India is the seventh largest country in the world.
Are ordinary light bulbs rated in terms of luminosity or brightness?
Yes, ordinary light bulbs are rated in terms of luminosity (which is generally understood as a measurement of brightness) AND voltage AND current. And physical size AND type of base (screw in, bayonet and which size?).There are many parameters that a light bulb can be rated by.
How do you describe a Samsung Galaxy s4?
You may describe it as slim or shiny. You can also describe it's size, screen brightness, and how it feels(smooth).

What is Massachusetts' rank in size?
Massachusetts is the 44th largest state in the United States in terms of land area.
What causes the apparent brightness or size of stars constellations and galaxies?
The size of stars depends on their mass and the stage of their life cycle. Constellations are just stars which happen to lie in the same general direction from Earth, and have nothing really to do with each other. Apparent brightess of a star or galaxy is the result of its intrinsic brightness and its distance from us.
