This can be a bit depressing because astronomers never find any planets that are remotely like Earth's mass except some uninhabitable moons, asteroids and planetoids that are far too small, basically existing as flying rocks. Not to mention that there are hundreds of criteria for a worthy planet, but these two criteria have proven impossible to find after centuries of studying space, this past 75 years revealing tremendous information on new planets, but nothing of real use. But what about Gliese 581C? Scientists were raving about this planet, plus it's not too far from us if humanity built a fusion pulse starship (is discussed in an article by me called "Project Daedalus"). This planet actually has 5.6 times the mass of Earth. So if you weighed 100lbs on Earth, on Gliese 581C you'd weigh 560lbs. And if you weighed 180lbs, well then you'd weigh 1008lbs!
Let's put it another way, if you were the strongest man on Earth and only weighed 50lbs you still could not survive on that planet. Your body's cells would stretch downward and burst from the gravity even though your muscles might be strong enough to hold you up. Your nose would bleed nonstop and your veins would snap like rubber bands under the downward forces of gravity. Your heart would not be able to pump your blood while standing! Honestly, you'd have an equal chance of breathing in outer space without a spacesuit than living on this planet.
you should know that it is only in Christ that we can find peace and joy!
