the reason this is important to note, is that in central force fields, angular momentum is conserved and the motion of a body in a central field is then constricted to move in two-dimensions, on a plane. that allows us to use polar coordinates to completely describe its motion. stars and planets wallpaper. using energy and angular momentum conservation we can do a little bit of calculus and differential equations to get explicit formulas for how the radius and polar angle of the planets trajectory change in time. the curves formed by these trajectories is a conic section. this procedure can (in principle) be done for any potential that acts like (a / rn ). an interesting anecdote: when the motion of uranus was first being tracked using these equations of motion, some irregularities were observed in its orbit.

a new theoretical planet was proposed to account for these perturbations. stars and planets wallpaper. that prediction is what started the search and discovery of neptune. because of the dynamics of orbits, and because of the many influences on the orbits of planets, circular orbits are rare. also, elliptical orbits don't tend to circularize over time, for the reason that a circular orbit is not a lower-energy solution than an elliptical one. a circular orbit is just an elliptical orbit with an eccentricity of zero. over time, a planet's circular orbit would likely become elliptical through the influence of other planets. stars and planets wallpaper. an elliptical orbit is a constant-energy solution. a typical elliptical orbit's kinetic and potential gravitational energy always sum to a constant during all phases of the orbit. as a result, there's no tendency to circularize an elliptical orbit.
