Any massive enough object will be in "hydrostatic equilibrium". Usually that means "pretty close to spherical", though rapidly rotating bodies may be oblate spheroids instead.
in term of shape
sphere
Earth is more of an oval compared to all the other planets.
Oval or elliptical shaped. (Not a perfect circle)
gas and shape
well the Earth is not exactly the same to other planets actually, it is the same because they're all parts of the solar system and they pretty much spin in the same direction but their features/characteristics are not much similar. Neither it is in size nor in appearance sooo....Hope this helps !!
the sun earth and the remaining planets are roughly spherical in shape.
Mainly size, density, distance from other planets, distance from the nearest star, existence of satellites, age, shape, (The Earth is flattened on its poles.) and many other features.
Aristarchus proposed the heliocentric model of the universe, suggesting that the Earth and other planets revolve around the Sun. This was a major contribution to Earth science as it challenged the prevailing geocentric model and laid the groundwork for our modern understanding of the solar system.
The SHAPE of the orbit the Earth and most planets and other bodies of mass in space are usually elliptical.
no
Approximately spherical, but because of the speed of their rotation, there is certain 'oblateness' - a little flattening of the shape on the poles. The shape that results is often called a 'geoid'.
