I think it is. The spot next to it is Jupiter's "Great Red Spot" which is said to be the size of three Earths across. Comparing that spot to the size of North America on this image, it seems pretty close.

if north america was that size, you couldn't even fit one earth in there, let alone three. North america needs to be about the size of texas for this to be accurate.
to whoever says this isn't accurate: Jupiter could fit like a thousand or something earths inside of it. and you wouldn't not be able to stand or travel to it because it's a gas planet and it's gravitational pull would crush you
When people say it isn't accurate, I'm pretty sure they're saying its TOO big, which I agree with. America would have to be about 1/3 of the earth for this to be accurate.
