Oh, and the thing to remember here is, I'm doing all of this off the top
of my head, without Googleing or any other 'looking up'. Just from what
I learned in Geology in HS and college.

And remember my paper I mentioned about the Earth heating up prior to an
Ice Age. From research that has been done since, I've discovered that I
probably hit the nail on the head.

Al Gore be damned!

All hail Al ;-)

I would disagree with your assertion that all the planets are revolving
around the sum in a "line", different distances from the sun require
different revolutionary speeds to maintain orbit, therefore different
points in their orbits relative to other planets occur regularly.

As to energy produced by the sun and a significant increase or decrease in
that energy, it would be readily measured by scientists who study the sun.
No big announcement in that area of study AFAIK.


But you gotta think of the inertia, grqavity and how all the planets are
captured.

Let's see, if my memory serves me, Mercury, Venus Earth and Mars are
grouped together, then there is an asteriod belt, then a ways out is
Jupiter.

I believe the inner 4 planets are similar to each other, while the last 5
planets (screw those scientists that blasted Pluto) kinda do a bit more
'free thinking'. So, it would be interesting to see what's happening on
Mercury and Venus.

So far, good, inner planets as rocky spheres, Outer four as gas giants, Pluto as odd man out so to speak. Temperatures as a function of distance from the sun, exception being Jupiter, which, according to planetary astronomers, emits more heat than it receives from the sun.

For millions of years, Earth emmitted more heat than it got from the sun. The Earth was hot after it formed and took a long time to cool off. In addition, the earth is still making heat from radioactivity, so it is probably still giving off more heat than it gets from the sun.

------------------------------------------------------------------------------------------------------------------------------------------
No problems with the above except that by this point in time the earth is not, AFAIK, emitting more energy than it is receiving from the Sun. Its core is still molten because of radioactive heat generation, according to scientists

If there is radioactive heat generation, and the earth is cooler than before, the only way that the only way the earth is not getting significantly warmer is if the heat is being radiated away from earth.

However, this heat is very tiny compared with the amount of heat it gets with the sun.

So, tehcnically, I am correct.

For all practical purposes you are correct (except for planets outside of the solar system).

Jupiter, afaik, is the only planet with output greater than input. Speculation is that Jupiter is a failed sun (lucky us) that has enough compression of matter to generate significant (measurable) heat in excess of its energy from the sun.

Actually, having another sun might be cool. Having a second sun would be cool at night depending on Jupiter's location. If it provided significantly less heat, then it would not cause much warming of Earth. It it were as strong as the sun, it would provide around 6% the energy of the sun, though which would probably significantly change the climate when the earth is nearer jupiter.

For a ball of gas to become a sun, it needs about 13 times the mass that Jupiter has (you can look up the exact number in Wikipedia).

But the point is where is Hachi going with this tread?

The earth is warmer by a few degrees than it would be without CO2 and other greenhouse gases. And Venus is a lot warmer than it would be without CO2 in its atmosphere.

Info on surface conditions on Mercury, Venus, and Mars is available, with varying degrees of detail, as is info on the outer planets. Connections with our current situation?


Can't find any info to support your position on Earth radiating more heat than it receives. However, I did find interesting info that not only does Jupiter emit more heat than it receives from the sun, but so does Saturn and Neptune. I stand corrected (or at the least, updated), theory for the heat generation is called: Kelvin-Helmholtz mechanism.

Where does the heat energy generated by radioactivity in the Earth's core go?
