Is Earth a perfect sphere?
Even though our planet is a sphere, it is not a perfect sphere. Because of the force caused when Earth rotates, the North and South Poles are slightly flat. Earth’s rotation, wobbly motion and other forces are making the planet change shape very slowly, but it is still round.
Why do celestial bodies spin?
Our planets have continued spinning because of inertia. In the vacuum of space, spinning objects maintain their momentum and direction — their spin — because no external forces have been applied to stop them. And so, the world — and the rest of the planets in our solar system — keeps spinning.
Is there a celestial body that does not rotate?
Venus, in particular, rotates in the opposite direction of how the solar system is spinning as a whole. The Earth will never be non-rotating, but Venus will if it lasts that long.

Which planet rotates the fourth fastest?
Jupiter completes a rotation on its axis in about 10 hours. The solar system has eight planets, which orbit around the sun. Out of the eight planets, six rotate around their axis in the same direction besides revolving around the sun. Jupiter is the fastest spinning planet while Venus is the slowest.
Is Venus hot or cold?
The average temperature on Venus is 864 degrees Fahrenheit (462 degrees Celsius). Temperature changes slightly traveling through the atmosphere, growing cooler farther away from the surface. Lead would melt on the surface of the planet, where the temperature is around 872 F (467 C).
Why is Venus called Earth’s sister?
Venus is a terrestrial planet and is sometimes called Earth’s “sister planet” because of their similar size, mass, proximity to the Sun, and bulk composition. It is radically different from Earth in other respects.
