Question

why the earth all planet, sun ,moon are round?

Answer 1

they are not round. they are in sperical shape because The myth that the Earth was flat persisted far longer than it should have. Philosophers and scientists suggested the Earth was round as far back as Pythagoras, or perhaps even further, and Eratosthenes even calculated its circumference with decent accuracy in the second century BC. It went on for centuries more, ultimately culminating in that most basic satisfying piece of evidence: the photo. In 1967, TIROS-1 sent down its blurry, poorly framed picture of the Earth as seen from space. Not even the most scientifically illiterate person could now doubt the facts. Earth is a sphere.

Answer 2

Sun is center of Solar System and is of biggest size therefore have maximimum gravitation due to which all planet hold each other around Sun. Now planets too have gravitational force therefore the Moon is holded around the planets.But none of them is round shaped perfectly instead due to gravitation they make a shape.
