No. A planet can't be perfectly spherical because of tidal forces.
Tidal forces happen when an object is large enough, that the gravitational pull on one side of the object is considerably larger than the gravitational pull on the other side of the object. To be classified as a planet, an object will be large enough that it will experience enough tidal force to alter the shape of the planet. Because of these forces, planets become shaped like distorted ellipsoids.
What else can I help you with?
Are any planets square shaped?
NO. It's part of the definition of a planet that it has to be spherical, more or less.
Are dwarf planets any shape?
Dwarf planets are primarily spherical in shape due to their self-gravity, which pulls them into a rounded form. However, they can exhibit slight deviations from perfect sphericity, often appearing slightly elongated or irregular due to their rotation, surface features, or any past collisions. Examples include Pluto, which is mostly spherical, and Haumea, known for its elongated shape. Overall, while they can vary somewhat, dwarf planets are generally closer to round than irregular.
How do you determine that other planets in our solar system are round?
By definition, a planet must be round (or at least spherical enough to be called that); a planet is any celestial body with enough mass that its own gravity forms it into a spherical body. The bodies we now call planets are known to be this way because of measurements in their orbits and calculations regarding them, as well as measurements of the planet itself via satellites and probes.
How does gravity affect the other planets in the solar system?
"Gravity" is responsible for the existence of planetary orbits, and for their shapes and periods. It's also the reason for the spherical shapes of the planets, and for the existence of atmospheres, in the case of those planets that have any.
What causes the earth and other planets to have more or less spherical shape?
The force of gravity pulls objects toward their center, causing them to form a spherical shape over time. Planets and other large celestial bodies are able to overcome any irregularities and form into spheres due to gravity's influence on their mass and density.

Do dwarf planets have any-life form?
None that are known. Earth is the only place in the universe known to have life and it is highly unlikely that any of the dwarf planets in our solar system have any life.
Do any planets have no moons?
Of all the Major planets only Mercury and Venus have no known natural satelites.
Why do planets look like a perfect circle from a distance?
It's part of the definition of "planet". An asteroid or meteor can have any shape, because its gravity isn't great enough to crush it into a mostly-spherical shape. But planets ARE massive enough that they have to be spherical; their gravity forces them into that shape. If their spin is fast enough, the equatorial regions will bulge out, such as with Earth and especially with Jupiter.
What would have to happen in order for Earth to become a perfect shape?
For Earth to become a perfect shape, it would need to be perfectly spherical. This would require it to have a uniform distribution of mass and no geographical features like mountains or valleys. Achieving a perfectly spherical shape would mean Earth would have to be completely smooth and free of any irregularities.
Is their any life on any of the planets?
Well, certainly no intelligent life, anyway. (The only known life at this time is on Earth, which is one of the planets.)
Why you know that the moon is spherical?
In the vaccum of space any object around 500 miles in diameter is forced to be round under its own gravity. Thats why all the planets are round.
