The shape of the Earth is actually a rather complex figure called a geoid, which just means "Earth-shaped". It's roughly an ellipsoid (which is itself pretty close to a sphere), but one where the Southern Hemisphere bulges just a tiny more than the northern one, making it very slightly pear-shaped (with additional bulges in various places).
If by revolution you mean the spin on it's own axis this is more or less a perfect circle. If you are referring to it's orbit around the sun, this is elliptical, not a perfect circle.
The Earth rotates in not a perfect circle around the sun but in a oval shape.
a circle

Earth's shape is oblate spheroid.

Earth's eccentricity Eccentricity is defined as the difference in shape between an ellipse and a perfect circle. In a similar fashion to Earth's obliquity, the more uniform Earth's orbit is (more like a perfect circle), the less difference there is in climate change throughout the year.
It is a nearly perfect circle.
A circle has no eccentricity because it is a perfectly symmetrical shape. The eccentricity of a shape is a measure of how much its shape deviates from being a perfect circle, so for a circle, the eccentricity is always zero.
Earth's orbital path around the Sun is an ellipse, not a perfect circle. This means that Earth's distance from the Sun varies slightly throughout the year. The shape of the orbit is very close to a circle, with the eccentricity being only 0.0167.
About the same shape as an egg, or oblong. Not a perfect circle.
The Earth rotates in not a perfect circle around the sun but in a oval shape.
Oval or elliptical shaped. (Not a perfect circle)
The Earth rotates in not a perfect circle around the sun but in a oval shape.
The world is a "oblate spheroid" because it is not a perfect circle. The Earth bulges out around the equator.
You can take a round cup or glass and set it in the middle of the paper and then taking a pencil you can trace the outer edge of the cup. You should have a perfect round circle upon completion.
the moon isn't a perfect sphere its kinda like a oval in a way The shape of the moon is an oblate spheroid, just like earth
