The reason we see elliptical orbits is because they are the stable orbits (those in which the velocity is not great enough to expel the body from the gravitational system) if you have specific questions i'd be glad to address them but look to other threads here if you want the proof of what i've said. It is important to realise that the orbits of the planets do not actually look elliptical the difference between the masses of the sun and a planet is enormous, and if you could look down onto the orbit of a planet and trace its orbit, it would look circular.
Why are orbits not spiral-shaped update cancel ad by quora for business i can recommend reading about kepler's laws to give you more information about how the elliptical orbits work, but until you see how newton's laws apply, you probably won't be satisfied now this does not truly explain why inverse square law forces produce a.
A planet's path and speed continue to be effected due to the gravitational force of the sun, and eventually, the planet will be pulled back that return journey begins at the end of a parabolic path this parabolic shape, once completed, forms an elliptical orbit. Most of these orbits are very nearly circular, but once again, to be considered circular they have to be perfectly circular ok, that horse is beaten to death :-) while the familiar objects are in elliptical orbits, there are a lot of objects that fall into the sun on a spiral path comets die this way all of the time.
We answer your astronomy questions please browse our archive first why do planets have elliptical orbits (beginner) if spacetime is curved, is it possible for us to look into space and see light from earth from long ago (intermediate) editor's pick. An elliptical orbit is the revolving of one object around another in an oval-shaped path called an ellipse the planets in the solar system orbit the sun in elliptical orbits many satellites orbit the earth in elliptical orbits as does the moon in fact, most objects in outer space travel in an elliptical orbit. Why do planets have a elliptical but not circular orbits a circle is a special case of an ellipse, whose eccentricity is zero so a circular orbit is an elliptical orbit with zero eccentricity.
Ignoring the details, you can see that this conserved quantity is intimately related to the elliptical orbits in my opinion, this is the lesson that is generalizable (and hence the answer to the question of why): look for conserved quantities and if they exist, they will let you solve the problem.

Why planets' orbits are elliptical and not circular the solar system condensed out of an interstellar dust cloud the original cloud was not a perfectly symmetrical object, either in shape or in composition, and as it condensed , the result was not neat or orderly there were lots of collisions as well as near misses that altered planetary orbits. Why is the moon's orbit elliptical shaped follow question 3 great question asked by glopro (8326) like the sun and the earth, for example the satellite appears to be orbiting around nothing it looks like a halo around the smaller body there are satellites out there at this very minute in that position all orbits are elliptical.
The stars in the halo move in randomly-oriented orbits, while the disk stars generally stay confined to moving in the disk which of the following statements describes the orbits of stars within most elliptical galaxies galactic disk (looks like band of light) features quizlet live quizlet learn diagrams flashcards mobile help.
