Galaxies are generally disk shapped, rather than spherical because of centrifugal force: Just like throwing a Pizza crust in the air, it expands in the direction of its rotation. However, older galaxies (possibly the products of collisions of two or more galaxies) can result in blob-shapped galaxies that are more spherical.

What is a small spherical object that orbiting the sun?
It sounds like a planet to me.
Compare and contrast the three types of galaxies?
Galaxies that appear to have a bulge in the middle and arms that spherical outward, like pinwheels, are spherical. Elliptical galaxies look like round or flattened balls. Galaxies that do not have regular shapes are known as irregular galaxies.
Does dark matter relate to a supernova?
Probably not. Dark matter is not believed to concentrate well in or around masses the size of stars. But it does concentrate well around galaxies and clusters of galaxies. Most of the mass of a galaxy like ours is believed to be in a sphere of dark matter in the galaxy's spherical halo.
What is the difference between plane waves and spherical waves?
spherical waves at far distance act like plane wave
What does a galaxy rotate around?
I believe the current understanding is that galaxies (that are not part of local groups of galaxies) don't orbit anything. There is no universal center, matter seems to be distributed more or less evenly no matter what part of the sky we observe, and the galaxies are moving away from one another according to the current established principles. Some galaxies are members of groups of galaxies, and perhaps some of these groups are slowly turning on an axis, a little bit like materials in an accretion disk.
What are galaxies that are round and disk-like called?
They are called elliptical galaxies.
What is a small spherical object that orbiting the sun?

Why are most galaxies formed like a disk?
A galaxy is formed when a nebula collapses under the force of gravity of the matter that it contains. The process of collapsing imparts a rotational momentum to the galaxy. It is this rotational motion which gives galaxies their characteristic disk shape.
Is the milky way considered a clump of stars?
No. It is a disk-shaped galaxy, like a pinwheel, with several curved radial arms and a large mass at the center. The closest thing to a "clump" of stars are the so-called "globular clusters" which are more spherical in organization than other common galaxies.

What is three dimensional galaxies that can be shaped like a football that can be shaped like a football?
I think elliptical galaxies are the galaxies you are referring to. Scientist normally describe them as a flatted disk shape. These galaxies contain mainly older stars.
What galaxy is shaped like a disk?
Most galaxies are shaped like a disk. It's the way they are formed. One of the most beautiful is the Sombrero Galaxy. [See related link for a picture]
What object in space do not directly orbit the sun?
Planetary satellites, like the moon; other stars, galaxies.
What does a black hole look like in 360' view?
A spherical blackness surrounded by orbiting stars with an accretion disk about its equator. I have provided for a related link to an artistic expression of a black hole accretion disk.

What is an object that is slightly smaller than Pluto and orbits the sun beyond Neptune and is spherical?
it looks like a big piece of badalhoca
If earth were not a spherical object what would have happened?
in order for it not to become spherical, it would have had to be much smaller. if it was much smaller, it would just be some rock floating around like the millions of similar rocks orbiting the Sun.
