Write an equation for the orbit of each planet. Assume that the centre of the orbit is the origin and the centre of the Sun is a focus that lies on the x−axis .
Calculation:
Consider the standard equation of the horizontal ellipse which is centred to the origin,
x2a2+y2b2=1
Length of major axis, 2a units, length of minor axis 2b unit and foci are at (c,0) and (−c,0)
The valid equation is,
c2=a2−b2......(1)
Consider the table for distances,
Assume that planet Venus revolves around the Sun in an elliptical orbit with the Sun at its one of its focus on x−axis .
The length of major axis will be the sum of closest and farthest distances and diameter of the Sun which is 0.87million miles. So now,
2a=66.8+0.87+67.72a=135.37a=135.372a=67.685
Now find c which is the distance from centre of ellipse to the focus, equal to minus the close sets distance and radius of the Sun (0.87/2=0.435) .
c=67.685−66.8−0.435c=0.45
Now put values of a=67.685,c=0.45 in equation (1) .
(0.45)2=(67.685)2−b2b2=4581.056725b=67.684
Now put a=67.685,b=67.684 in x2a2+y2b2=1 we get,
x2(67.685)2+y2(67.684)2=1
Hence, the equation of the orbit of Venus is , x2(67.685)2+y2(67.684)2=1 .
Now consider the closest and farthest distance of Jupiter from the Sun,
2a=460.1+0.870506.42a=967.37a=483.685
c=483.685−460.1−0.435c=23.15
Now substitute a=483.685 , c=23.15 in equation (1) .
(23.15)2=(483.685)2−b2b2=233,415.2567b=483.13
Now put a=483.685,b=483.13 in x2a2+y2b2=1 we get,
x2(483.685)2+y2(483.13)2=1
Hence equation for orbit of Jupiter is x2(483.685)2+y2(483.13)2=1

Which planet has an orbit that is closer to the circle?
Calculation:
Consider the standard equation of eccentricity of ellipse is,
e=ca
For Venus planet put a=67.685,c=0.45 in above equation,
ev=0.4567.685ev=6.6484×10−3
For Jupiter planet, a=483.685 , c=23.15 ,
eJ=23.15483.685eJ=47.8617×10−3
Thus lesser the value of e more circular the orbit of ellips,
Hence, the orbit of Venus is more circular.
