Wow. Thanks for calculating that. I'd have to go back and study up to do that. :)

So that'd make the day'night variability almost nil, and probably give that strong magnetic field I mentioned earlier.

No! Only the mass below you will contribute to the gravitational attraction,

Which is what I said as well.

How are scientists sure that those radio and television transmissions continue to travel?

They will, but will spread out and weaken per unit area as the square of distance. But given what the programming is and its usual content, I suppose it is just as well.

If they saw any of the MSM and figured it out, they would probably show up with Roach spray and end our misery.

Planet sounds more like an uncomfortable, tidally-locked rathole than anywhere I'd want to emigrate to. Seriously - the only way anyone from Earth would be comfortable there would be in the water.

It's still an awesome discovery, though. Perhaps the next one found will be a little nicer.

Me, I'd prefer ~1G, atmo at 14psi made of 70% N, 25% O2, and 5% N2O, 4:1 ocean to land ratio with several small continents and lots and lots of islands, all orbiting a nice G-class star between 90 and 100 million miles while rotating on its axis once every 20 to 30 hours.

Oh yeah - it MUST have a nickel-iron core to generate a magnetic field. Wouldn't want my Eden getting bombarded by cosmic rays and solar flares.

But with my luck, it would have some kind of airborne Ebola-like virus floating around in the air that kills humans in minutes, or super-fast, hyper-oxygenated species of carnivorous Grendel that thinks of us as tasty little hours d'ouvres.

(Hats off to Niven and Pournelle for that last one)

The big problem with this is that it’s so close to the red sun that the tidal pull would probably cause the same side of the planet to face the sun all of the time, much like the moon always has the same side to the earth. Thus, one side would be scortched, the other would be freezing.

That occurred to me as well. Kinda like that old "McDLT" from McDonalds - "keeps the hot side hot and the cool side cool".

The place sounds more like a penal colony for child molesters, mass murderers, and deposed dictators, forced to mine dilithium.

"Welcome to the penal colony of Ruhre Penthe! Work well, and you will be treated well. Work poorly, and you will be exiled to the surface!"

Take Venus, for example - its gravitational pull is much less than Earth's however its atmosphere is crushing as it simply has more atmosphere.

Actually, Venus' g-field at the surface is 90.4% of Earth's.

What happened there was the fact that Venus' rotation period is so slow (243 days, retrograde), and it's so close to the Sun, that its water boiled off early. Any life it might have had died off before it had a chance to develop photosynthesis and lock Venus' CO2 in carbonate rocks.

Slow rotation and close to the Sun, no water. No water, no life. No life, no oxygen, and a runaway greenhouse effect.

End result: the closest thing to Hell that we have in the Solar system, with 900 degree highs and clouds of sulfuric acid.

You forgot:

- Porn star Cicciolina wins a seat in the Italian parliment

- Les Miserables is awarded 8 Tony awards, including Best Musical.

- The marriage of Charles and Diana starts to deteriorate, they begin living alone.

(Something tells me that these three events are related.)
