What following terms refers to an object that orbits the sun and has enough gravity to be spherical but has not cleared the area of its orbit?
The term that refers to an object that orbits the sun, has enough gravity to be spherical, but has not cleared the area of its orbit is "dwarf planet." Dwarf planets, like Pluto, meet the criteria of being round due to their self-gravity but share their orbital zone with other objects of similar size. Unlike full-fledged planets, they do not dominate their orbits.
Why planets are round in shape?
Gravity. It pulls the various parts of the object toward the center. Gravity increases with mass. Extremely massive objects, like planets and the larger asteroids, have enough gravity that the object must assume a roughly spherical shape.
How do planets becomes spherical?
The quick layman's answer is 'gravity'. Imagine an object with the same over-all density and mass as the earth, only it is in the shape of a solid cylinder 100 miles in diameter. It would be (for just a brief moment) like a wire stretched out over a very long distance. It could never maintain such a shape; the object would still have gravity, and the ends would quickly and catastrophically collapse toward the center. This would be quite a thing to witness. By the time all the crashing and exploding comes to an end, the mass would be roughly spherical. This is just to visually illustrate the idea of gravity pulling the mass into a spherical shape; in fact some of the impacts may be so great that some of the material might be propelled at such a velocity that it would never return.
Why is the flame spherical in space?
In space, flames become spherical due to a lack of gravity to pull the flames upwards. The absence of gravity causes the flame to burn in all directions uniformly, creating a spherical shape. This phenomenon is known as a "cool flame" and is different from flames on Earth, which are affected by gravity.
Why you know that the moon is spherical?
In the vaccum of space any object around 500 miles in diameter is forced to be round under its own gravity. Thats why all the planets are round.
What is the center of gravity for a spherical object?
The center of gravity for a spherical object is located at the exact center of the sphere. This point is equidistant from all points on the surface of the sphere, making it the point where the force of gravity can be considered to act on the object.
What do you call an object smaller than a planet but with gravity too weak to form a spherical shape?

What determines how strong the force of gravity is at the surface of each planet?
The weight of an object on the surface of a planet depends on ...-- The mass of the object.-- The mass of the planet.-- The distance between the center of the object and the centerof the planet, i.e. the planet's radius.
Is your earth spherical if yes then how?

What is the most spherical object in the universe?
The most spherical object in the universe is believed to be the star Kepler 11145123, which is nearly perfect in its spherical shape.
Does each planet have to rotate or have wind to become round?
The round (spherical) shape of a planet comes about through the force of gravity, not through wind, but the rotation does have an effect on its shape. Mass is related to gravity, the more massive an object is the bigger the force of gravity at its surface. If an object is around 700-1000km in diameter (roughly) then it will have enough gravity for it to shape itself into a ball shape, overcoming the internal forces that would otherwise give it an irregular shape. A object (like a moon, dwarf planet or planet) has to be large enough and massive enough to 'pull' itself into a spherical shape. The spin of the object may cause the spherical shape to become squashed, if it is fast enough, as the centripetal forces at the equator will stretch it out somewhat.
State four requirements needed to be considered a planet?
To be considered a planet, an object must orbit the Sun, be spherical in shape due to its gravity, and have cleared its orbit of other debris. It should also not be a satellite of another object.

What is an asphericity?
An asphericity is a state or degree to which something is not spherical.
