Well, not really.
But one of the most enduring images from the Star Wars trilogy is Luke watching the two suns of his home planet Tatooine set.
Two suns for one planet.
And our own lovely earth could have had them.
When the solar system formed from instellar gas and dust, most of the stuff that didn’t fall inward and form the sun was condensed to form Jupiter. If Jupiter had been just a few times larger, its interior would have started thermonuclear reactions, and become a bonafide shining star. Even now, Jupiter gives out more than twice as much energy as it receives from the sun, and gives out enough energy in the infra-red spectrum to almost be considered a star.
So, depending on how you look at it, Jupiter isn’t necessarily the giant planet bully, but it’s just a failed star, a washout.
Jupiter isn’t so hot now, eh? King of the gods, hardly.
It’s just fascinating to imagine what would have happened to the earth had Jupiter actually become a star. What would have happened to days and nights? Would we even have nights? If there were no nights, would life have evolved the same way? What about the crucial day-night cycles of the biological clock? Circadian rhythm? The counter regulation of the metabolic clock? Would humans/mammals have ever evolved (since sleep, either diurnal or nocturnal, is so essential for survival)?
Would I have been Luke Skywalker?
(Interestingly, I recently read that Alpha Centauri, the closest “star” to the solar system and earth, isn’t just one star, but a THREE star system. Two stars orbit each other, and a third, Proxima Centauri, orbits these two. Now, if these stars had planets, and if they had life, it must be a sad life out there, with no night, and perhaps no sleep. Isn’t sleep the best thing about life?)
