since all the planets have different orbits around the sun,then howits possible,sun is a common foci for all the orbits?according to kepler's law of gravitation?please explain

Dear praveen

Basic equation of ellipse is

It is locus of point soch tha its distance from two fixed point is always constant

PS1 +PS2 =constant

is suppose S1 and S2 (focie of ellipse is fixed) then for different value of constant you will ge different elipse.

similarly for different orbits we will get different constant but focie will remain fixed

see this figure
