Gravity pulls everything towards the center. Any large elevation would be flattened by gravity.This question has been laying heavily in this mind of recent.The sun must have great gravitational pull in order to keep the entire solar systems planets in such precise rotation speed and fairly predictable celestial events.A mass such as the sun generating that much gravitational pull to it core or focal point baffles me how it doesn't consume our entire solar system as if acting as a black-hole with much less density of course.Or the planet earth with its solidified magma core and very malleable surface rotating on its poles at high speeds would create a much more outward pull at the equator even more so as the earth reaches the closest orbit of earths journey around the sun should create an almost disc like form from the pull of the sun coupled with earths molten core and the rotation achieved as earth passes around on the path that somehow has been laid as all planets in this solar system....not creating a spherical orbit of our planets around the sun similar to an atom's protons and neutrons rotation but more like a spiral with long outstretching arms not a spherical structure but more flat as a whole and expanding not growing smaller or to a center.Any thoughts on this matter would be very appreciated as this mind like many others tends to question the whole basis of time space and the insatiable need to find out the answer to the eternal question...why
The inner planets (Mercury, Venus, Earth, Mars) in our solar system are all roughly spherical in shape due to their gravity compressing their material into a spherical form. They lack the mass to maintain a more irregular shape like some larger moons or asteroids.
Its the same reason as to why every other heavenly body is spherical in shape. its because any rotating body in order to conserve energy takes the shape involving least tension and hence your planets, moons are spherical in shape.
The moon is observed to be nearly spherical in shape because of the gravitational forces acting on it. Over time, moons and planets tend to form into a sphere due to their own gravity pulling inwards equally from all directions, which results in a spherical shape. Measurements from spacecraft and telescopes have also confirmed the moon's spherical shape.
The force of gravity pulls objects toward their center, causing them to form a spherical shape over time. Planets and other large celestial bodies are able to overcome any irregularities and form into spheres due to gravity's influence on their mass and density.
The sun is a sphere, while planets are generally spherical in shape due to gravity pulling their mass evenly in all directions. Some planets have slight deviations from a perfect sphere due to rotation or geological activity, but they are still predominantly spherical in shape.
Mars' moons are much smaller than, for example, Earth's Moon, or the larger moons of Jupiter. A large moon will have a larger gravity, which will tend to pull the moon together into a spherical shape.
Most but not all larger MOONS (bodies that orbit planets, moons, or asteroids) accreted in the same way that PLANETS did, assuming a variable density and a nearly spherical shape. Very large moons such as Titan have many of the characteristics of planets: vulcanism, atmospheres, and weather. Generally speaking, moons orbit planets in the same way that planets orbit stars.
Since all of the planets, and moons, and stars seem to have a spherical shape, it is possible that the universe may be a sphere.
No. Only the larger moons are spherical. Smaller moons do not have strong enough gravity to make themselves round and so are irregular in shape. Perfect example are Phobos and Deimos, the two tiny moons that orbit Mars.
The inner planets (Mercury, Venus, Earth, Mars) in our solar system are all roughly spherical in shape due to their gravity compressing their material into a spherical form. They lack the mass to maintain a more irregular shape like some larger moons or asteroids.
The inner planets have a spherical shape. In fact all planets are more or less spherical.
There are two planets with an almost perfectly spherical shape. They are Mercury and Venus.
Planets, moons, and stars are round due to gravity. Gravity pulls objects towards their center of mass, causing them to form into a spherical shape. This is the most stable and efficient configuration for large celestial bodies.

Planets are all spherical.
Spherical
The planets mass creates gravity which pulls it into a spherical shape. This is the difference between planets and other heavenly bodies such as moons and asteroids. To be defined as a planet, a body must have enough gravity to pull itself into a spherical shape and it's gravity must be sufficient to clear its area of other debris.
