When it comes to the solar system, every planet It is essentially circular. Does the situation change if we look at the entire universe?

Bride, the answer to all these questions Let’s give it.

Planets must have enough mass to produce the gravitational force needed to make them spherical.

At the same time, according to researchers, one of the conditions for being a planet is that they are round. they have sufficient mass. However, this does not mean that the planets are necessarily perfect spheres.

So while we think of planets as round, in reality they are not perfectly round. We are in this Included on Earth.

On the other hand, Earth and similar planets have a bulge around the equator due to the outward force experienced by a rotating object.

These protrusions are quite subtle, but still have significant significance. Because centrifugal force creates objects At the equator it weighs about 0.5% less than at the poles. has.

But centrifugal force isn’t the only force that can change a planet’s shape. If the planet is close enough to the parent star, the gravitational forces acting on it become so great that the effect occurs changing shape of the planet can cause.

In addition, some scientists have suggested the existence of a donut-shaped planet.

However, this is very unlikely. For such a thing to be possible, a planet’s centrifugal force must be greater than the force of gravity pulling the planet’s mass toward the center. It should weigh more.

Apparently this claim is more science fiction than science. In summary, planets generally have a round shape. However, this round shape is not perfect.. Various protrusions or minor changes in shape may be possible due to the reasons mentioned above.
