Uranus is approximately 2.74 x 10^9 km away from the Sun at perihelion and 3.00 x 10^9 km at aphelion. Find the eccentricity of Uranus's orbit given that the perihelion is r = a(1 - e) and the aphelion is r = a(1 + e).

  1. so, plug and chug.

    a/(1-e) = 3.00*10^9
    a/(1+e) = 2.74*10^9

    a = 2.86*10^9
    e = 0.0453
