Why are all planets Spherical/globe like?after,all who's heard of a square planet.?

Answer 1

Planets are spherical because of gravity. When an object is massive enough to be a planet, means that it has enough gravitational pull towards its center to pull it from all directions (360 Degrees) downwards and level them in a spherical shape. The bigger the object the more gravitational pull it has.

If an object/body has a shape other then that of a sphere, that means that the object isn't massive enough to produce the amount of gravity needed to pull in itself. Generally bodies like these are called 'Dwarf Planets (like Pluto)' or meteors.

Also note that not all planets are 100% spheres. The earth for instance is a spheroid, meaning it looks like a slightly flattened spear. This may be due to the Earth's composition of elements, geological effects or rotation.

Answer 2

all matter is made up of compounds of elemnents that are made of aoms - he building block of everything in the world . They are round for the simple reason tha right from its ist standard ( the basis single component ) atom , the electron is revolving around the proton. revolving is gooing round and the two particles , electronand proton areexerting some force of attractioin on each other . the electron being an active component always running in a staight line is being pulled towrds the center by the protonand thispull and the force of the movement of theelectron create a resultant force , a centrifugal force and this keeps theelectronin a circular orbit arond the nucleus of the atom.Now the electromnw which is spinning around the nucleus is in a circular orbitand it exerts a foce that is equal all around the atom . So evey atomn has its foce equally around itself and the grat masses tha form on account of the acrual of the atoms continue to pexet pull around themselves and towards the center andall these atoms that are held tight together have thier pull toward the center of the mass .It is only in the shape of the globe the force from the center can be of equal strenght all aorund and any ohter shape will cause an inequality and and disturb he center of gravity and equillibrium of the the mass. All masses have a force of attraction in proportin to thier mass and in inverse proportioin to the square of hier distance. The increase in the force of attraction is due to the increase in the quantity of mater present in the mass and if the mass should be in equillibrium the force it should have its force of gravity in the center. In any shape othere than the globe the force exerted from the center of the mass can not me equal onall sides of the mass of the body . Since the mass has a tendency to pull everything towards its center , the force around the cener is spread equally on sides and points on the surface of the mass only in the case of the globe and it is in that shape the surace area is the most minimum. ; because the force pulls all the atoms of the elements of the mass towards the center and all the matter get compressed towards the center.Only in a globe all points on the surface are locateda the sameand equal distanceform the center. No ohter shape would ensure this . so all matter that acrues in to a single mass in nature always tend to form a round and global shape only .Even lare quantityof gases would do the same in the abcence of any disturbance by any current of air or any ohtrer force ,.

Answer 3

I think it's something to do with the fact the the planet's centre of gravity pulls everything towards it (the centre of the planet) and the pull is even all the way round, so it is therefore spherical. It's like bubbles - you can't blow a cube-shaped bubble can you? That's because the pressure is the same all the way round it.

Answer 4

To put it simply and not go into too much detail, planets were originally formed of material put out by large combustions of stars, etc. A large object of this "!waste material" will naturally have a stronger gravitational field. It pulls in more materials and increase in size, thus becomes larger and has more gravity pulling in more material. Until it reaches a limit were the gravitation field is now in equilibrium (not strong enough to pull in other material, but strong enough to hold the material it has together to become one object...a planet!)

Because gravity has no horizontal/vertical limit it attracts from all directions, creating a spherical shape of any material it pulls in.

Answer 5

Planets are spherical due to the opposing forces of rotation and gravity on them - the only possible shape they could be is a sphere, as these forces are constantly pulling against one another.

Answer 6

It is because of how the forces of gravity interact with the rocks or gases that make up the planet and the vacuum of space. Each planet has a core - or exact center of gravity. Rocks and gases are pulled around that gravity center. Because space is three-dimensional - it wraps around in the form of a sphere.

I hope this makes some form of sense. It is really hard to explain.

Answer 7

gravity is pulled at 360 degrees thus creating a spherical globe. if gravity was pulled at 4 equal corners then you would get your square planet.

Answer 8

alpha 204/3/6/7 is a moon that rotates jane 299/4/5 in the Xeres Nebula... it's square on one side and spherical on the other.

Answer 9

its made that way due to the force of gravity seeming to act on a single central point. a star/ planet is round due to the fact the matter making it up moves so the force is equal around it. All stars / planets would be smooth spheres but they are 'bumpy' due to natural occurances on the inside (or reactions on the outside like solar flares)

Answer 10

Rotational forces pull planetary mass into a roughly spherical shape.

Cirric - mountains are rounded because of erosion, it's nothing to do with gravity & rotation

Katiekcat5 - the Earth isn't pear-shaped, it's an oblate spheroid (a slightly flattened sphere)
