The planets' orbits are elliptical, not exact circles. Still, that doesn't alter the
answer too much.
Two things combine to give the planets their stable orbits:
1) The velocity of the planet, which, at any moment, is " tangential"
to its orbit. (That's, roughly, "sideways" in ordinary words.)
2) The gravitational attraction of the Sun, which is always directly towards the Sun.
(If you can do the mathematics it becomes clearer.)

What is the relation between SHM and uniform circular motion?
Simple Harmonic Motion (SHM) involves an oscillating motion back and forth around a central equilibrium point, while uniform circular motion involves an object moving in a circular path at a constant speed. The two are related in that the projection of uniform circular motion onto one axis can produce SHM, such as the motion of a pendulum. Mathematically, SHM can be described using trigonometric functions that are similar to those used to describe uniform circular motion.
Was rudolphine tables based on uniform circular motion?
Yes, the Rudolphine Tables, compiled by Johannes Kepler, were based on the motion of planets in elliptical orbits around the sun, rather than uniform circular motion. Kepler's laws of planetary motion provided a more accurate description of the planets' movements compared to previous models based on circular orbits.
What is the difference between uniform linear motion an uniform circular motion?
linear is which is on a straight path and circular motion is which has a curved path. *In a uniform linear motion,the velocity is constant and the acceleration is zero.So,uniform linear motion is an unaccelerated motion. *In uniform circular motion the velocity can be variable although the speed is uniform.So,it is an accelerated motion.
What are two kinds of circular motion?
translational motion and rotational motion
Which of following is best example of uniform circular motion?
A car driving around a circular track at a constant speed is a good example of uniform circular motion.
Is planetary motion a uniform motion?
Planetary motion almost fits into the category of Uniform Circular Motion. Uniform Circular Motion is an object moving around a circle of constant radius at a constant speed. The planets fill all of these requirements except for the fact that their orbits are slightly elliptical. Their orbital paths are almost perfect circles, but they are so close that for Uniform Circular Motion problems, it is not likely that considering the orbits to be circular will produce an incorrect answer.

What is circular motion?
Circular Motion -a motion along a circular path or the motion of an object in a circular Example -blades of a ceiling fan when the fan is switched on. or The motion of body along the circular path is called circular motion
Is uniform circular motion is accelerated motion?
if an object moves along a circular path, the only change in its velocity is due to the change in the direction of the motion. The motion of the object moving along the circular path is, which is a uniform circular motion, is therefore an accelerated motion:):):):/
Is the motion of earth a uniform circular motion?
yes the motion of earth around the sun is uniform

Uniform circular motion.

Is uniform circular motion and circular motion is the same?
no, in uniform circular motion the magnitude of your velocity, and therefore your acceleration is constant. in general this does not need to be true. consider this simple experiment, in a children's playground, go to a roundabout. stand on the roundabout and kick once, then wait for your motion to completely stop before kicking again. your motion is still circular, but neither velocity or acceleration is constant.
