If the solar system were placed to the edge of the galaxy, the majority of the night sky would be black with few stars.
<h3 /><h3>What is Galaxy?</h3>
A galaxy is a collection of stars, stellar remnants, interstellar gas, dust, and dark matter that is gravitationally bound. The name comes from the Greek word galaxias, which translates to mean "milky" and refers to the Milky Way galaxy, which houses the Solar System.
Because stars are more prevalent near the galaxy's core and less at its extremities, if the Sun and Earth were transported to its edge, we would observe mostly black skies at night and few stars.
We may thus draw the conclusion that if the solar system were transferred to the edge of the galaxy, the most of the night sky would be black with only a few stars.

Answer:
![C=\epsilon_{o}\frac{\pi R^_{2}}{d}](https://tex.z-dn.net/?f=C%3D%5Cepsilon_%7Bo%7D%5Cfrac%7B%5Cpi%20R%5E_%7B2%7D%7D%7Bd%7D)
This result is a very good approximation, because R>>d
Explanation:
The capacitance for two parallel flat plates, with surface S, space between them d, is:
![C=\epsilon_{o}\frac{S}{d} =\epsilon_{o}\frac{\pi R^_{2}}{d}](https://tex.z-dn.net/?f=C%3D%5Cepsilon_%7Bo%7D%5Cfrac%7BS%7D%7Bd%7D%20%3D%5Cepsilon_%7Bo%7D%5Cfrac%7B%5Cpi%20R%5E_%7B2%7D%7D%7Bd%7D)
This calculation is based on the fact that the electric field is constant between the plates. This only happens if the area of the plates is much larger than the distance between them: S>>d, i.e. R>>d. If we assume these factors, the result has a very good approximation.
