It would appear that our new poster in this thread believes that painting the bull's eye around the arrow indicates accuracy.

Re: Eris the tenth planet
So, according to your 'logic', we've got at least ten planets then. Eris being one of those.

Much more than that. It would appear that the single characteristic a "planet" needs is to orbit the Sun, so we have hundreds of thousands of planets, perhaps even millions, and that is just in the asteroid belt.

Re: Precision in Nature: Evidence of God or Accidents?
You are the only person between us two who thinks that to be the case. If the other planets did not have their own field of gravity, the sun would have been able to suck them in.

Hehe, this is actually getting funny.

Re: Precision in Nature: Evidence of God or Accidents?

Short summary: The mass of the planet determines the speed of the satellite (and of course other aspects of the satellite's orbit).

What the statement does NOT say is that more massive satellites move faster or slower or in different orbits than less massive satellites. I believe that misconception to be the source of your error.

Now when we consider the solar system in light of our (new??) understanding of the quote, we see that for the solar system the SUN takes the place in the quote of the massive planet while the PLANETS, because they orbit the SUN, take the place of the satellites.

So substitute SUN for 'massive planet' and PLANETS for 'satellites' in your quote and observe the result. In this case, there is no substitute for 'lesser mass planet' in the quote because there is no second SUN for the planets to orbit. But we can say that if we considered planets orbiting the massive star Betelguese, that the quote accurately suggests that such planets would have to move faster their orbits that would planets a similar distance from our sun Sol.

Or to put it in simpler terms, the centripetal force created by the circular orbit must equal the force of gravity that is acting in the opposite direction. Gravity increases with the mass of the star, and decreases with distance.

Just think of how your hot wheel cars are able to go around the loop and stay stuck to the track.

Re: Precision in Nature: Evidence of God or Accidents?
Yes, I read all that. And as I previously stated, a "dwarf planet" is still by definition a planet.

No, it isn't. A dwarf planet is a dwarf planet. A planet is a planet. They are two different things.

Even worse, your definition of planet is simply something that orbits the sun which would make all of the comets and asteroids planets as well, so we actually have millions of planets in the solar system according to your redefinition of planet.

Re: Precision in Nature: Evidence of God or Accidents?
The source also says that the satellite "must move faster in its orbit," indicating that the satellite's own gravitational forces are a contributing factor

When the difference in mass is very large the satellite has very little effect. If the satellite is large then the larger mass will noticebly wobble because both bodies are orbitting around their shared barycenter. A see-saw is a good analogy.

Quantum mechanics does not help your argument. Here's why: Quantum mechanics is nothing more than a THEORY.

In science, Theory is as good as it gets. There is nothing more than a theory.

The elements on the Periodic Table are so precise . . .

What makes them precise?
