<br />Gregg, Where did the information of the several properties of Sedna come from? Do you have a link to the source of this data?

Jim

From articles in the Science or Space categories on news networks on the internet. Comments came from the astronomers who discovered Sedna and other astronomers. About 6 sources. No one made any reference to collapsed matter.

Ok then what caught my eye was the color and emission-points 4&6. Do you have any more info about that?

I have not seen any quantified information on the Sedna spectrum.

<br />if the planet were collapsed matter, and had 10,000 times the mass we would attribute to it, could its inertial mass enable its highly elliptical orbit to remain, more or less, the same?<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">Just a quick note on this one point. The answer is "no". If Sedna were 10,000 times the mass we attribute to it, it might wreak havoc on other planets; but its own orbital path and the stability of that orbit are completely unaffected by the body's own mass. Remember the Tower of Pisa experiment, or astronaut Scott's "hammer and feather" experiment on the Moon's surface? All objects fall at the same rate from a given point in a gravitational field.

See our Meta Research Bulletin article "Does gravity have inertia?", to which we answered "no". -|Tom|-

Tom,

Care to comment on the failure of the Hubble Space Telescope to find any moons orbiting Sedna?

Everything over 1000 km diameter (which includes Sedna), and probably most things over 500 km diameter, are likely to be escaped moons of now-exploded planets rather than explosion fragments with debris clouds in orbit. Escaped moons from explosions are quite unlikely to have moons of their own.

That said, I nonetheless remain skeptical that the survey was anywhere near as complete as claimed. If the Hubble had such resolution capabilities, it would have resolved moons for some large asteroids with confirmed moons discovered by star occultations. -|Tom|-
