Earth orbits the sun in an elliptical pattern. The equation of Earth's path is.... where the measurements represent millions of
Triss [41]

General equation of Ellipse centered at (h,k) is given as

\frac{(x-h)^{2}}{a^{2}} + \frac{(y-k)^{2}}{b^{2}} =1\\

where a is the radius along x-axis

and b is radius along y-axis.

Given : The equation of elliptical path of Earth as

\frac{(x+2.5)^{2}}{22350.25} + \frac{y^{2}}{22344} = 1\\

Comparing the equation with the general equation, we get

(h,k) as (-2.5,0)

a = \sqrt{22350.25} = 149.5

b = \sqrt{22344} = 149.48

We have the Sun located at the coordinate (0,0).

Hence, the distance between Sun and Earth in July = 149.5 + 2.5 =152

∴ Earth's distance from the Sun in July is 152 million kilometers.
