What makes our planet rotate and orbit the sun at a precise uniform rate? How come it does not waver?

Because we have an awesome Father in heaven who created it that way. The big bang theory can easily be disproved by demolition of anything with T-N-T. We are taught in school that order was created out of the chaos of the big bang theory, yet in every instance of T-N-T being used for anything, chaos and destruction resulted. If the big bang theory is true, then every time a bomb explodes, or a volcano erupts or some form of chaotic event occurs, we should see a complex universe formed from it's aftermath. Along with that universe, we should see life form from the ashes. \n\n   Nothing but death and destruction has ever followed. The world is exactly where and how it is, doing exactly what it is supposed to do, at exactly the right angle, with exactly the right rotation, at exactly the right speed, because the God who created this universe created it that way. It will continue to work as it does until He makes it stop. That's just the way it is.

because of the differing sizes of each planet the time it takes each planet to rotate differs. we also have to factor in the speed at which each planet is rotating.

It is more like they are falling around the Sun. Earth is always falling into the Sun, but it's sideways orbital speed keeps moving Earth to the side of it's direction of fall. So the direction it would have to fall to hit the sun keeps changing and Earth has to keep starting over to get up speed falling in the new direction. This just keeps going on forever, falling toward the Sun but always missing it to one side. Of course, this takes enormous speed on the part of the Earth, about 66,000 miles per hour sideways all the time. Closer planets must move sideways faster, because they are closer to the Sun and are pulled down to it more strongly than distant planets. So Mercury moves much faster than Earth and Pluto much slower. But it is the same principle.

Stars and planets form as a result of the gravitational collapse of accreting material. Any net translational motion of that initial material is accelerated as its radius of rotation decreases. This is due to the same conservation of angular momentum principle that makes skaters and divers spin more rapidly when they bring their arms closer to their bodies. In its extreme, this effect can make collapsed neutron starts spin many times each second, creating the regular beat of pulsars as observed from Earth. \n\nOnce an initial spin was established for the Earth, the same conservation principle says that its angular momentum will continue unless it can be transferred to another object. With no significant frictional forces to allow that to happen, the Earth can continue to spin indefinitely without any further prodding. (More on that later.) \n\nIt is incorrect to say that the Moon does not spin. It rotates on its axis in synch with its revolution around the Earth, keeping the same face always pointed toward us. If it did not rotate at all, we would see all of its surface over the course of one month's orbit. This condition was created by tidal forces between the Earth and Moon, gradually slowing its initial rotation until the current more stable situation evolved. This same 'tidal lock' condition has been observed for satellite closely orbiting other planets. Because of its elliptical orbit, a slight 'wobble' allows us to actually see slightly more than half of the Moon's surface over the course of a month. \n\nTidal forces, by the way, continue to affect the Earth/Moon system. They exert enough frictional force on the Earth so that some of its angular momentum IS being transferred slowly to the Moon. The net effect of that is to gradually slow down Earth's rotation and lengthen the day. Where is that energy and momentum going? The moon is gradually receding from the Earth. Both of these effects are small. The Moon is receding at a rate of less than 2 inches per year and the day is getting longer by one second every 67,000 years or so.

When the Sun has Sunspots you can see that they revolve around the Sun.\n\nIt basically rotates similar to how the planets rotate.\n\nRotate not orbit.

The effect known as the Gyrous of Rotation causes planets to spin. When the planet is born and begins to condense out of its accretion disc it contracts and this puts a turning moment about the planets common centre, similar to a ballet dancer pulling in their arms in order to spin faster. JULES

The sun never stops shining.  The earths rotation brings us into the shadow of the earth for part of every day.  If you wer far enough north in the summer or south in the winter then the sun would never dip below the horizon while it appeared to circle around the sky.

That's a really good question, that doesn't have an answer yet.  The current theory of solar system formation suggests that planets spin in coordination with the orbital spin of the disk of matter that forms the core of the solar system.  The spin of the accretion disk itself is the result of conservation of angular momentum, and can either be clockwise or counter-clockwise, which would be a relatively random process.\n\nThere are 'accidents' however, whereby planets are impacted by other large bodies in random ways and can greatly skew the planetary orbit and/or spin.\n\nSometimes the results are really weird, such as Uranus, which rotates top-to-bottom relative to the plane of our solar system.\n\nFrankly, until we're able to do a survey of planets in our galaxy and a few others, I think it would be hard to guess what the real averages would look like, and whether or not they are random.

Spin relative to what?\n\nThe spin of the Earth about its own axis causes day and night but only because the spin is not synchronised with the orbit of the axis around the sun.  Mercury spins once on its axis for every orbit and so always has the same face to the sun.  It could be said in this case that Mercury does not spin, but that is only relative to the orbit of Mercury.\n\nImagine a frame of reference that is fixed in space like the grid lines on a map.  If a planet did not spin on its axis relative to this reference, then it would have a day/night cycle that took one orbit to complete (this would be one year for the Earth).\n\nIt is also believed that the spin of the Earth contributes to the generation of the magnetic field, so if the spinning stopped or slowed (relative to any reference) we could loose the magnetic field and thus be exposed to higher radiation levels from the sun.

The sun rotates on its own axis that what causes the gavational pull to keep the planets moving around it.

The Sun does indeed rotate. different part of sun rotates at different time. its like jupiter. \nA rigid body such as the Earth will clearly have a single rotation rate. But since the Sun is made of gas, different parts of it rotate at different speeds. Near the Sun's equator, it completes one rotation every 27 Earth days. But near the poles, it's about 31 Earth days. This is called "differential rotation".

Because it's not a solid body, different areas of the Sun rotate at different speeds.\n\nEQUATOR - 25 days per revolution\nPOLES   - 36 days per revolution\n30-degrees above/below equator - 28 days

The sun DOES rotate! It also revolves.

The Earth is continually rotating on its axis.\n\nIn short, the Earth rotates because it has to in order to help conserve angular momentum in the universe.\n\nThere is a physical Law which states that angular momentum must always be conserved.\n\nThe big ball of gas and debris which out solar system was formed from had some value for its angular momentum (even if that value was zero).  When the sun and the planets formed from that material, in order to conserve the angular momentum, the planets and sun started rotating.  If you add up all the angular momentum there is now between all the planets/the sun, moons/.... it should come out to be the same value as the angular momentum of the material which formed out solar system.

Earth is revolving in orbit, held in place by the Sun's gravitational pull

It goes back to when the solar system was formed.  The sun (and the planets, for that matter) were formed when a gigantic cloud of gas and dust collapsed.  When that cloud collapsed, it had something called 'angular momentum', which really just means that it was spinning a little bit.  When a large, slowly spinning thing collapses to something smaller, the rate of rotation speeds up (think about an ice skater that pulls her arms in...she spins up!).  Anyway, so now we have all this gas and dust in a disk that's orbiting the new Sun.  The dust eventually forms into planets.  As the dust collapses into new planets, the same thing happens, and the planets start spinning themselves.  So basically, the earth and moon and whatnot spin because of angular momentum.  I hope this made sense/helped!

The planets are actually trying to move in a straight line at a high speed due to the intertia from some force long ago.  When two objects are moving by each other, their gravity interacts and pulls them toward each other, bending the path that would otherwise be a straight line.  If they are too massive and too close, the gravity pulls them so much that they collide.  If things are balanced just right, the path is bent into a complete ellipse.  It's an ellipse instead of a circle because the sun is actually also being pulled a tiny bit toward the earth, as well.\n\nYou could consider gravity to be sort of a "perpendicular inertia", and the planets would revolve around the sun FOREVER if there were no other forces involved.
