hey friends it is well known that orbit of a planet is elliptical and this is also known that an elliptical has two centres so my question is who is at the another focii because at one centre sun is located so what is there?
samikshasingh224:
actually its true that sun's original position is not known but we can't say there is nothing
this is only said because we don't know what is there
my question was that is it compulsory whenever this will be discovered so is there will be a star
like sun

Actually the sun is not on any of the focii of the ellipse. May be it will be of some planets but not all. And there's nothing at the other focus.
I think it doesn't need to be at one of the focii necessarily.
''necessarily''
Due to the force of gravity, which goes as the inverse of the square, planets trace out an ellipse in space as they orbit around the sun, which is located at a single focus. The other focus is unphysical.
Actually, given two massive bodies, their "difference" vector will trace out an ellipse with the center of mass at the focus. Because the sun is so much more massive than most of the planets, we can usually disregard this since the center of mass is located within the sun itself

u can even check it out in Google that it is situated at one of the focii
and yes u r right still it is accepted that there is nothing
