How Does Earth's Potential Energy Change from Perihelion to Aphelion?

[Robertoalva]

Earth's distance from the Sun varies from 1.47 multiplied by 1011 m at perihelion to 1.52 multiplied by 1011 m at aphelion because its orbit is not quite circular. Find the change in potential energy as Earth goes from perihelion to aphelion.

ΔU=GMm ((1/r1)-(1/r2))

The Attempt at a Solution

i don't have any idea of what the value of m is

 

[SteamKing]

How about M?

You know, this is the internet. You could always look it up.

 

[Robertoalva]

G= gravitational constant
M= mass of the sun( or the object that is being orbited.)
m= the object orbiting.

 

[SteamKing]

Well,do you know what values to use for G, M, and m?
