Beautiful day at South pole

As the Earth continues to turn as a function of its orbital motion the Sun is now permanently in view . On a planet where discoveries are now rare due to the dominance of an extremely loud bunch of people with poor convictions, this one is for those who can enjoy the spectacle that the Earth turns once to the central Sun and parallel with the orbital plane.

Yes, doing one circuit of the sky every 24 hours:

Pick a spot on the moon and it will remain in view from a central Earth as it runs it monthly circuit, pick a spot on the Earth's surface such as the South and North poles and they turn completely to the Sun as it runs its annual circuit. The entire surface turns this way but is swamped by daily rotation however when these rotations combine we get the seasons.

The reason the Sun is in view this week and not for the last 6 months comprise an insight that should delight the mind as it is something new yet has been going on for as long as life existed on this planet.

That's because the Moon turns once as it orbits the Earth, keeping (roughly) the same face towards the Earth, while the Earth's axis does not turn as it orbits the Sun, staying fixed with North pointing near Polaris.

Try it yourself: walk around a tree anticlockwise keeping your left arm pointed at the tree and your right arm pointed in front of you. As you circle the tree, your right arm points N, W, S and E, then N again. Your left side is presented to the tree at all times. You are "turning".

Now point N in front of you, and walk around the tree while facing N at all times. You present your back, your right hand side, your front and then your left hand side to the tree, but you point N at all times.

The first circuit was like the moon - turn once per circuit and present the same face inwards. The second is like the Earth, point N throughout and present all sides to the Sun.

But I am probably wasting my breath here, as you don't understand basics like turning and pointing at things.

It is always strange to see someone use an analogy that was first presented in this forum for the last 10 years but of course the analogy is botched .

The surface rotation as a function of the orbital motion of our planet or any other for that matter is parallel to the orbital plane and perhaps the unique rotational and orbital traits of Uranus present the roughly 4 degree change over the course of an Earth year -

The rings and the zonal flows due to daily rotation help observers distinguish between the dual rotations whereas images of the Earth from space make it less clear apart from the Antarctic continent however people can now see dual rotations in action for both planets -

Again, it is strange to see my own analogy used against an insight that would appeal to reasonable people as they become familiar with the planet's two day/night cycles and their respective rotations.

You didn't try the turning and pointing thing. You never will.

He has used the moon one before. It feeds his credulous superstitious
nature. What he can't realise is that the moon doesn't "look" at Earth.
It's just held on an elliptical orbit while rotating at a steady rate.
That's why Mate Orientale won't be visible for a while.
Pick an object on the moon and it will always be visible he wrote.
He was wrong of course.

Another interesting exercise is to consider that the Moon is
essentially in orbit around the Sun, not the Earth. If we were to
remove the Earth, the Moon would continue in nearly its current path
around the Sun, orbiting at 1 A.U. over one year, and rotating with
its month-long day. I wonder how that fact fits in with Gerald's
geocentric view?
