it was developed in 410 B.C.
John Dalton imagined atoms to be indivisible and solid spheres that were akin to billiard balls. He believed that atoms of different elements had different sizes and weights, and that they combined in simple whole number ratios to form compounds.
Jupiter is spherical but its core is the only substance that is a solid
The spherical solid core of the earth. It is an alloy composed mostly of nickel and iron.
As with all planets it is an oblate spheroid
It has a solid core which forms a small part of its overall mass.
the indivisible solid sphere was invented in 1803 by John Dalton
John Dalton imagined atoms to be indivisible and solid spheres that were akin to billiard balls. He believed that atoms of different elements had different sizes and weights, and that they combined in simple whole number ratios to form compounds.
The indivisible solid sphere model, also known as the billiard ball model of the atom, was proposed by John Dalton in the early 19th century. He suggested that atoms are indivisible spheres that make up all matter and that they combine in simple whole number ratios to form compounds.

Democritus and John Dalton both believed that atoms were indivisible and made up all matter. They shared the idea that atoms were small, solid particles that could not be divided further.
Balls can be spherical or not. The (American) football uses a ball that is far from spherical. However, a sphere is a perfect geometrical solid with a uniform radius, and a ball made in that shape is quite suitable for games. It will, for instance, bounce in a predictable way.
solid angle is the ratio of the intercepted area dA of the spherical surface , described about the apex O as the centre ,to square of its radius r
The word is "planet".
A ball is a spherical or approximately spherical body shape. It is also a round or roundish body, of various sizes and materials, either hollow or solid, for use in games, such as baseball, football, tennis, or golf.
