Question

explain me that " why all planets orbit is circular except pluto and mercury..."??.

Answer 1

All planets in the Solar System have a Fricking elliptical orbit..this is soo wrong

Answer 2

For pluto-
Well Pluto’s orbit and its relation with Neptune’s, is pretty stable, but NOT in the long run. You see Pluto is a not massive (it is only 0.00218 Earths), and its orbit is influenced by all kinds of small perturbations (mainly from Neptune). It has not cleared its orbital path. Its mass accounts for only 0.07 of the collective mass of objects in its orbit
That's why it has elliptical orbit.



For mercury,same reason would apply.
