Here is the moon and Earth, with sizes and distances to scale.
Light takes two seconds to get from the moon to the Earth, so what you see in the night sky is the moon two seconds ago.
If you make the distance between the moon and Earth 390 times larger, that's the distance between the Earth and the sun.
If you make the distance between the moon and Earth 107 million times larger, that's the distance between the Earth and the next nearest star, Alpha Centauri.

I can't help feeling I'm missing something. I kept looking at the attachment and waiting for an alien or something to suddenly appear on screen. Seven hours, I waited.
If your intention was to illustrate how far Earth is from Alpha Centauri, well, thank you. I kind of knew the distance was enormous but thank you anyway. You are now free to point out how stupid I've been.

Lol! The image is oversize. Scroll the image from left to right.
It's like the laptop lid all over again.

I would like to congratulate everyone on their increasing maturity. Not one of you asked Mince about Uranus.
-
;D
-
Did you know that Mercury is on average the nearest planet to Uranus?
-
It can be a problem.

[Diane: Tarks started this!]
Did you know that Uranus is huge and you can see it with the naked eye?
Did you know that Uranus is full of gas and produces a lot of wind?
Did you also know that Voyager 2 took loads of photos of Uranus in 1986 and now the EU want to probe it?

Moot point. I think, in fact, it was Diane.

On Sunday morning, I will be travelling above the Earth for about three hours before touching down in Faro, Portugal. The temperature is predicted to be 27 degrees. I have no idea what the temperature on Uranus is.

I have no idea what the temperature on Uranus is.
That depends on whether the sun shines out of it.
-
Okay - I'll give you that. ;D

I'd hoped to avoid stuff like that by saying "ON Uranus" rather than "IN Uranus".

Ah, I misread. I doubt Uranus gets to see much light, but if Uranus had a black hole in it, that would change things.
-
Please stop. Stop now.
-
I note that Diane has not been back to survey this whole mess that she started.
-
I refuse to take responsibility, however I will give a (*nono*)

If you shrank the sun to the size of a pea, the Earth would be a speck of dust, and the next nearest star would be 220km away.
And the observable universe would be 3 trillion km in diameter.

Blimey! Hope no-one actually does it then.
