Question 1197617: Word Problems (Ellipse)
The planet earth comes closest to the sun at 147 million
km, and farthest from the sun at 152 million km. Thus,
its orbit is an ellipse for which the two vertices are 147
and 152 units away from a particular focus, the sun.
Find the equation of this ellipse, assuming that the major
axis is horizontal and the center at the origin. (units to be
in million km.)

let say the sun is located in focus whose coordinates are (,), -> (,) and -> (,)

two vertices are and units away from a particular focus (,) (so, left and right from origin)
vertices are at (,) and (,)-> (,) and (,)

vertices differ units, so the other focus will be units left from origin at (, )
center is half way between: (, )=(, )
=>,
find :

find :

your ellipse is:
