Because as much as we Know/Learn the more we realize that we have learned/know nothing. As much as i love science unfortunately the only TRUE reality is that MOST of what we think we know is only speculation and is still not concrete fact. So to sum it up I would not disrespect you by trying to answer that question with a rotation and gravity answer as it was taught/explained to me. Take a look at this to get the TEXT BOOK ANSWER and good luck!!!!

What else can I help you with?
What planets are not round?
How round are we required to be? All the planets are spherical, due to gravitation. None of the planets are perfect spheres, due to rotation, tidal effects, surface irregularities, etc. If you are thinking of celestial objects other than planets, small ones under 300 kilometers in diameter (or up to 600 km depending on their composition) can be very odd shapes because they have insufficient gravity to form them into spheres.
When the moon is completely illuminated and perfectly round it is a?
Full Moon
Is Mars round?
The planet Mars is round in shape. All of the planets in our solar system are orbits. The gravitational pull of the sun has formed the planets to be around.
What do you call the space between planets?
The space between planets is known as interplanetary space. It is mostly vacuum but can contain small amounts of particles and gases.
WHY is it that only jovian planets have ring?
Jovian planets have rings because their strong gravitational forces can capture and maintain orbiting particles and debris that form the rings. This is due to their larger size and mass compared to terrestrial planets. The rings around Jovian planets are made up of rock, ice, and dust particles that orbit around the planet in thin bands.
Is all the planets completely round?
Yes and no. They are round, but not perfectly spherical. For example, the Earth has a slight bulge around the equator. Jupiter and Saturn have more obvious bulges. Saturn in particular is flattened at its poles compared with its equator. Also, of course, the surfaces of the planets are not perfectly smooth.
What orbit has the eccentricity that is closest to 0?
Of the planets in our solar system, Venus has the smallest eccentricity.
How round is the moon?
it is perfectly round.
If Earth is round how can it be tilted?
the earth is not perfectly round, as with most other planets it is an oblate spheroid. Answer: The tilt refers to a tilt in the axis of rotation, compared to a line that is perpendicular to the Ecliptic (the plane of Earth's orbit around the Sun).
whats starts with p and round?
PLANETS ARE ROUND AND START WITH P SO THE ANSWER IS PLANETS ( i think )
What planets are not round?

Is the sun perfectly round?
yes
Is a circle perfectly round?
Yes
Can a dwarf planet be round?
Yes, dwarf planets can be round. Like regular planets, dwarf planets are large enough for their own gravity to pull them into a nearly spherical shape, making them round. Examples of round dwarf planets include Pluto and Eris.
When did the planets first Aline perfectly?
the year 1832
How do you move particles?
twist it round and round
Which planets has more of a spherical shape?
There are two planets with an almost perfectly spherical shape. They are Mercury and Venus.
