You mean perhaps 1.5^2?

Yeah, ~ 1.5x in relation to their respective aphelions (farthest orbital distance to the Sun)

But, yes - if you will - the area of the solar system consequently has more than doubled; which has nicer ring to it :)

To be exact if my numbers are correct:

πab = πa² √(1-e²)

Uranus (a = 19.19126 AU; e = 0.04717)

⇒ ~ 1155.755 AU²

Neptune (a = 30.07 AU; e = 0.008678 (what a neat circle!))

⇒ ~ 2840.54 AU²

i.e. approx. 2.46x the former area

This is certainly impressive, thanks!
