how many planets ike earth could ever exist at one time?

Answer 1

Since the universe is infinitely large, I'd say there's quite a few inhabitable planets like Earth out there. Scientists think that Alpha Centauri (4 light years) would be our closest habitable solar system. Assuming there's a habitable solar system every 6 light years from each other, we have a lot of systems to count with our infinitely large and expanding universe. We are just much too technologically challenged to get there!

BTW: The sun is 8 light minutes away and it would take a considerable amount of time (if possible at all) to get to the sun using our current technologies.

Answer 2

Billions...quite literally.
We've only begun to scrape the surface of what is known about the quantity of earth-like planets throughout the universe.
There's probably even planetary systems out there that don't even have a STAR like the sun at the center of it.

Answer 3

Since the universe is practically infinite, and the earth occupies about as much space as a speck of sand on a beach in it, i'd say an infinite amount.

Answer 4

confident. purely look at whales on earth. If there is one greater huge waterworld available existence in it oceans must be lots lots bigger than dinosaurs and whales. As for creatures residing on land length is a concern of necessity and a function of gravity. On a international with terrestrial gravity it takes huge quantities of energy to be important and flow around. the only earnings to measurement is in that it particularly is a defence against predators. And so the predators get greater desirable and better, that evolutionary tug of warfare. although at last length is purely too source hectic and the coolest deal approximately residing is complicated. purely bear in mind mating in case you finally end up a Bracciosaurus... On a international with no longer as much as terrestrial gravity evolution wouldn´t ought to provide you such haphazard sollutions like hollow bones to maintain the load down (do no longer ignore the cranium of the T-Rex). issues could get even greater desirable than dinosarus and it wouldn´t be a disadvantage. although a international with much less gravity could consistently be in risk nonetheless. It couldn´t be lots lighter than earth or it, like Mars, wouldn´t be powerfuble to maintain onto its very own ecosystem. Venus is lighter than earth and ought to guard onto its ecosystem so the region the sweetspot is is tough to declare precisely.

Answer 5

Around other stars? I don't think there's any limit to the number that *could* exist. We have no idea how many actually do exist - our telescopes aren't good enough to be able to see them, yet.

Answer 6

It is very unlikely that there are any planets like earth. We are possessed with self destruction.

Answer 7

Well I think that there is over 200,000,000,000 or more planets like earth in our galaxy. in the universe I'm not sure of.

Answer 8

an infinite amount.

Answer 9

A lot.
