    Idea Origin Water
AI Thread Summary
The discussion presents a hypothesis that the Moon was once a rocky terrestrial planet that lost its lighter volatiles, including water, during the Sun's T-Tauri phase. It suggests that all terrestrial planets within 1.5 AU experienced similar volatile loss due to solar winds. The author references Isaac Asimov's "Asimov on Astronomy" to support the idea that the Moon's unique gravitational relationship with Earth and its concave orbit around the Sun indicate it is a terrestrial planet. The hypothesis posits that Earth and the Moon will eventually share the same orbit as the solar environment cools, eliminating the need for a rogue planet impact theory. The thread invites further dialogue on these unconventional ideas, although it notes that new theories should be published in peer-reviewed journals for broader discussion.

TL;DR Summary
I wish to explore a new hypothesis for the origin of Earth's water. This new concept is complicated having many phases. I will break down these phases and explain them one at a time.
Simply stated the Earth's original orbit was between Mars and Jupiter close the the 'snow line' thereby having the ability to condense water on its newly forming crust.
A sample of the best consensus hypothesis that I will refute is (https://ui.adsabs.harvard.edu/abs/1991Icar...92...2P)
I will begin with the concept that the Moon was originally a rocky terrestrial planet that orbited at roughly one AU from the Sun and lost the majority of its lighter volatiles including water during the T-Tauri phase of the Sun's transition into a Main-Sequence yellow dwarf star. A similar loss of volatiles eventually occurred for all the other terrestrial planets within 1.5 AU due to the hot solar winds. A unique capture mode between Earth and Moon will occur in which these two planets, one bringing water, will share the same orbit after the Sun surrounding region becomes cooler.
I now refer you to a book, "Asimov on Astronomy" by Isaac Asimov published in 1974. In his chapter, 'Just Mooning Around' he provides compelling evidence of why the Moon is another terrestrial planet. Among some of his more important reasons are the gravitational pull between the parent planet and the Sun. The gravitational pull is greater for the Sun than it is for the parent planet for only one satellite in the solar system and that is Earth's Moon. Another amazing revelation is that the Moon's orbit is everywhere concave about the Sun unlike all the other satellites in the solar system. In my hypothesis, there is no need for a rogue planet to strike Earth and be slowed enough to begin re-coalescing and orbit Earth.
I welcome any ideas or dialogue about this 'outside-the-box' thinking. I will explain next how Earth finds a closer orbit.

New theories and alternative hypotheses must be published in an appropriate peer-reviewed journal before they can be discussed at PhysicsForums.

This thread is closed... but threads discussing some of the many unusual and interesting properties of the earth/moon system will be welcome.

Today at about 4:30 am I saw the conjunction of Venus and Jupiter, where they were about the width of the full moon, or one half degree apart. Did anyone else see it? Edit: The moon is 2,200 miles in diameter and at a distance of 240,000 miles. Thereby it subtends an angle in radians of 2,200/240,000=.01 (approximately). With pi radians being 180 degrees, one radian is 57.3 degrees, so that .01 radians is about .50 degrees (angle subtended by the moon). (.57 to be more exact, but with...
