Why are all the planets in the solar system round?
Question:
Answer:
I did some research for you, below is what I found:
"That's because of the nature of gravity. You can think of gravity as a force that points inward toward the center of the planet so that every part of the surface is pulled evenly toward the center, resulting in a spherical shape."
Good question. I have to assume they were created that way. Funny, God never has really been into squares has he?
As a moon, or planet is formed, and is stationery in an orbit of any particular galaxy, it is caused by its own gravity. the magnitude of the gravity doesn't matter, it comes directly from the moon or planets core, and eventually, forms a spere.
....Also, I think God sometimes likes to play Pool...
An interesting question. Now, the first question that comes to
my suspicious mind is "IS the earth round?" And the answer is no, at least
not perfectly round. But it is round compared to your average cube, that is
for sure! Now, my understanding of how solar systems form is pretty
inadequate; all I can tell you is what I see on "Nova." But basically, I
guess it has to do with gravity, which is a CENTRAL FORCE. What that means is
that gravity pulls things together along a straight line, and the more massive
one of the things is, the stronger it pulls. When the earth was forming, it
was basically a big ball of dust left over from an exploded sun (a supernova).
Gravity caused a lot of the matter to condense into a big fiery ball (our
sun), but some of the dust was far enough away from the Sun so that the
stronger forces were between planetary dust particles and not the sun. SO,
they swirled together into a ball. You can see something similar when you
make a painting with one of those "spin-art" machines; you put a card on the
spinner, which whirls around real fast, and then you squirt paint on the card.
The whirling causes the paint to go out away from the center (this is like the
explosion of the supernova) and droplets go out along an interesting path
until they stop, which happens when the spinning force is equal and opposite
to the force which attaches paint to the card (this is like gravity). Now, if
the force attaching paint to the card were not so strong,eventually the drops
would get bigger - "planets."
A sphere is the lowest potential energy solid. All points of a mass are attracted to the center of mass; as a solid forms, the particles distribute themselves to be as close to the center as possible; this results in a sphere.
All answers (almost) I beleive are right. Although, when understanding Einstein, you realize energy moving at the speed of light and potentially more, has its surplus of energy converted into mass. And that this created mass would look exactly like a planet...or star. i.e. perfectly spherical.
Do you see where I'm going with this?
