You just don't hear that anymore when you watch a show about astronomy.
Whenever I watch something like that my dad always says if the sun were a grapefruit...
So I thought if the sun really were the size of a grapefruit, how big would the planets be and how far away would they be from said grapefruit.
And here's what i got.

I won't bore you all with the actual facts, just the ones I got using a grapefruit that's 15 cm in diameter.

Diameter:

Mercury: 0,053 cm
Venus: 0,13 cm
Earth: 0,137 cm
Mars: 0,073 cm
Jupiter: 1,539 cm
Saturn: 1,299 cm
Uranus: 0,55 cm
Neptune: 0,524 cm
Pluto: 0,025 cm

Distance from the sun:
Mercury: 6,24 m
Venus: 11,66 m
Earth: 16,12 m
Mars: 24,56 m
Jupiter: 83,87 m
Saturn: 153,99 m
Uranus: 309,8 m
Neptune: 485,34 m
Pluto: 637,5 m

Next step is to make a scale model of the solar system. I'll probably just do the inner solar system, because the whole thing (even without Pluto, because it's not a planet) would be too big.

And I thought I had too much time on my hands...

Now I'm thinking of Ronnie Barker as Fletcher in Porridge Anyone else?

Knew I could rely on you Mandrake!!

If the sun were a grapefruit it'd get pretty cold around here

If the sun were a grapefruit it'd be massive.
