sphere
the sun earth and the remaining planets are roughly spherical in shape.
Yes, the sun's gravitational pull is what keeps Earth and the other planets in our solar system in orbit around it. This gravitational force is what maintains the planets' paths and prevents them from moving off into space.
The Sun and its planets are all basically spheres. The earth is an 'oblate sphere' - that it, it is flattened at the poles.
earth and all the other planets
Earth and the other planets are mostly made of rock.

Yes, the Earth and other planets in our solar system revolve around the Sun in elliptical orbits due to the force of gravity. This orbital motion is what causes the planets to move in their respective paths around the Sun.
The SHAPE of the orbit the Earth and most planets and other bodies of mass in space are usually elliptical.
The Sun, Earth and other planets, along with many other items are part of a Solar System.
The actual shape of the earth's orbit around the sun is horrendously complicated. Partly because the earth does not orbit the sun and also because the orbit is influenced by the the gravitational attraction of the other planets. The earth does not orbit the sun: the centre of mass of the earth-sun system is at one of the foci of an ellipse whose eccentricity is 0.0167. The eccentricity varies from 0.0034 to 0.058.
Without the planets orbiting the sun all the planets would be cold and dark
Beacuse earth has water air and Sun the moon has no air or no Sun or water only earth is a life planets the other planets are the same like moon they had no air or Sun and water
