Don't forget our moon at 2,000 miles Diameters: Sun: 900,000 miles Mercury: 3000 miles Earth: 8000 miles Moon: 2000 miles Puts Mercury into context of another familiar object. I'd round the sun to ~1 million miles in diameter. What's 100,000 miles between friends?

I have found that one significant figure is more than enough, and don't use km, even though metric has been adopted in all other parts of the civilized world. Diameters: Sun: 900,000 miles Mercury: 3000 miles Earth: 8000 miles During the transit, Mercury is about two-thirds of the way to the Sun. Placed at the distance of Mercury, the Earth would appear less than three times as large as the tiny, black dot.
