Every system in this universe tries to reduce its energy. The shape of bubble is always round because the area is minimum in case of sphere for a given volume, which in turn reduces surface energy.
its not perfectly round .It is because of continuous bombardment in plasma due to fusion of hydrogen and release of their energy.
Soap bubbles are round because of surface tension. The surface tension of the soapy water molecules causes them to pull equally in all directions, forming the most efficient shape, which is a sphere. This round shape allows the bubble to enclose the maximum volume with the least amount of surface area.
Nobody's head is perfectly round. It is a free-form shape. Everybody's is a different shape.
Is a circle.
Overal the shape of the planet Mars is round. However, there is some indentations in the planet that make it a little distorted and not perfectly round.
A cone, a section of a sphere.
It is a sphere
Bubbles are "generally" round due to the air pressure acting equally on them from all points around the outside of the bubble. A bubble is round as it is the most energy efficient configuration. The spherical shape also maximizes the ratio of the volume to the surface area.
A ball is typically spherical in shape, which means it is perfectly round in three dimensions.

To make perfectly round butter balls for your dinner party, you can use a melon baller or a small cookie scoop to scoop out the butter and then roll it between your palms to shape it into a round ball. Refrigerating the butter beforehand can also help it hold its shape better.
A word for "out of round" is "eccentric." This term refers to an object that deviates from a perfect circular shape, often resulting in an uneven surface or alignment. Another term that can be used is "oval," which describes a shape that is elongated and not perfectly round.
