I have to wonder, would you slide down to the sun, or be flung outwards? SDSpivey (talk) 19:39, 15 March 2023 (UTC)

The discs are centered on the orbit of the parent planet, and presumably rotating at the same frequency as the parent planet's orbit. That means the inner edge of each disc is going slower than you'd need to orbit the Sun at that distance, and the outer edge faster. If you moved inward from the original planet's orbit, the Sun's gravity would pull you in, but when you crossed the boundary to the next disc, you'd get flung back outward.162.158.62.61 19:58, 15 March 2023 (UTC)
No Each planet fills out the space within their orbit into the next planet. Easy to see as the outer edge of Neptune's orbit is the same as with the planet flattened. There is a distance from Mercury to the Sun indicated. Maybe because it would melt if it got any closer? --Kynde (talk) 20:03, 15 March 2023 (UTC)
First, they're rings not discs, but I'm skeptical of the math. And it looks to me like the ring's edges are halfway between the orbits, with Neptune extended outwards the same distance as halfway to Uranus's orbit. 172.69.22.4 20:08, 15 March 2023 (UTC)
Planet Volume (1010 km3) Orbital radius (109 km) halfway to prior halfway to next Annulus area (109 km2) Thickness (m)
Mercury 6.1 58 29 83 19000
Venus 9.3 108 83 129 30637
Earth 10.8 150 129 189 59942
Mars 1.6 228 189 504 685794
Jupiter 143100 779 504 1107 3051847
Saturn 82700 1434 1107 2154 10726236
Uranus 6800 2873 2154 3684 28061145
Neptune 6300 4495 3684 5304 45743348
The volumes in this table are at 2 different scales. Only the Mercury to Mars volumes are at 1010 km3. Jupiter to Neptune are at 1012 km3 Sandor (talk) 21:01, 15 March 2023 (UTC)
Thanks, fixed; I had the scale wrong for the radii too. 172.71.158.231 21:16, 15 March 2023 (UTC)

This makes about as much sense as other Flat Earth theories. 172.70.200.137 20:00, 15 March 2023 (UTC)

But this would actually be a flat Earth. Albeit with a rather larger surface area ;-) --Kynde (talk) 20:03, 15 March 2023 (UTC)
