@Hartmann -

Thanks for the cool video. I LOVE the music; can anyone identify it?

There's always Nemesis

Reading that little article ( Never heard about "Nemesis" before ), I couldn't help thinking about a quatrain from Nostradamus:

"Lune obscurie aux profondes tenebres
Son frere passe de couleur ferrugine:
Le grand cache, longtemps sous les tenebres,
Tiedera fer dans la plaie sanguine."

"The moon is obscured in deep shadows,
Her brother passes with a rusty color:
The great one hidden for a long time in eclipses
Iron will cool in the bloody wound."

Now, I don't want to claim anything.......

It really depends alot on exactly what you're talking about. If it just gets bright enough to heat Europa to Earthlike temperatures (which I believe is what happened in the novel 2010), all that happens at Earth is that Jupiter now appears really really bright.

You beat me to it. In the book Clarke worked it out that the new sun was pretty weak, only just bright enough to produce earthlike conditions on Europa, with the added heat to earth being trivial, although I wonder about Mars at closest approach.

Speaking of Mars, 2010 was the second time Clarke pulled that "two suns" trick. The first was in the novella Sands of Mars, where either Deimos or Phobos (I can't remember which) was detonated into a stable fusion reaction as part of Mars' terraforming.

Now I'd like to see *that* mod!

No, even Mars would be getting only about 1/730th of the light Earth gets from the Sun. This would be equivalent to the sunlight that an object 27 AU from the sun receives, a bit more than Neptune gets, in other words.

It would be swamped out by the sunlight Mars gets to start with.
