All right, so let's say we have five planets and we want to rank them according to their axial tilt with the smallest one, the lowest, and the largest one at the highest.
00:09
So we're told planet theta, which is number one.
00:12
We're told at the summer solstice, the sun is up for 24 hours over half the planet.
00:17
All right, so that kind of means our axial tilt, which we'll call, i suppose, alpha.
00:23
I don't think we have a letter for that.
00:24
The axial tilt there has to be 90 degrees because basically you have the sun illuminating half the planet over this entire day.
00:35
So it's rotating on its side.
00:37
And then planet two, we have planet delta.
00:40
We're told at noon the sun appears higher than it would on earth.
00:45
That's just going to mean it has a greater axial tilt than earth does...
