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.
A small spherical object orbiting the sun would be called a planet, asteroid, or comet, depending on its characteristics and orbit.
There are generally three types of galaxies: spiral galaxies, elliptical galaxies, and irregular galaxies. Spiral galaxies like the Milky Way have a disk shape with arms of stars spiraling out from a central core. Elliptical galaxies are shaped like ellipses and contain mostly older stars. Irregular galaxies have a less defined shape and tend to have a mix of young and old stars.
An elliptical galaxy is the type of galaxy that can have a rounded, ball-like or oval shape and is primarily composed of older stars. Unlike spiral galaxies, elliptical galaxies do not have prominent spiral arms, and they generally contain much less gas and dust. Because there is less material available for forming new stars, their stellar populations are typically older and often appear reddish in color. Elliptical galaxies range from nearly spherical systems to elongated ellipsoids. A nearly spherical example is Messier 89 (M89), which NASA describes as an elliptical galaxy that appears almost perfectly spherical. These galaxies are important for understanding galaxy formation and evolution. Astronomers believe many elliptical galaxies developed through collisions and mergers involving other galaxies, which helped shape their smooth structures and influenced their stellar populations.
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.
The sun is a ball-shaped star. It appears as a circle in the sky due to its distance from Earth, but it is a spherical object like other stars in the universe.
They are called elliptical galaxies.
There are three main types of galaxies: spiral galaxies (like the Milky Way), elliptical galaxies (oval or spherical in shape), and irregular galaxies (lacking a distinct shape). These classifications are based on the galaxies' shapes and structures.

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.
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.
Galaxies that are shaped like a sphere or an egg are typically classified as elliptical galaxies. These galaxies have an ellipsoidal shape, lacking the distinct structure of spiral galaxies, and can range from nearly spherical to more elongated forms. Examples of elliptical galaxies include M87 and the giant elliptical galaxy Centaurus A. Their smooth, featureless light profiles and older star populations distinguish them from other galaxy types.
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.

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]
