Title: Very earthlike planet found by NASA

So apparently Kepler 452-b is fairly earthlike. 60% larger, 50% older, and 500% 400% more massive, but in its star's habitable zone, and with a 50/50 shot of having a rocky surface. Its atmosphere would be thicker than Earth's, and we have no idea what its made of, but this is the most earthlike planet we've yet found.

60% larger... and 500% more massive

...Huh?

Straight from the NatGeo article


Quote
Kepler 452b is about 60 percent larger than Earth, and perhaps five times as massive.


Then again, I suppose that would only be 400% more massive, wouldn't it.

Now I'm not sure if that's actually an error, or "larger" and "more massive" really do mean different things in astronomy.

60% larger... and 500% more massive

...Huh?

1.6 times Earth's radius. Volume and mass are proportional to the cube of the radius.

We don't know the mass, though, so we don't know the density of Kepler 452b and we can only speculate whether it's terrestrial (Earth or Venus-like) or a smallish gas giant. It's technically a super-Earth and it's in a habitable orbit, but I'd hold off on calling it Earthlike without more information.

Or it could be 1.6 times Earth's volume, and 5 times Earth's mass. It's very possible if the planet is a lot denser.

Sort of, but not quite. Indeed in this case "60% larger" is talking about its radius (which is a weird way of putting it) but assuming a straightforward mass ∝ radius^3 relationship would imply the planet is 4.3 times* more massive, not five times. This is because planets of different sizes are also likely to have different densities, so while volume is proportional to radius cubed, mass is not exactly proportional to volume.

The "5 times more massive" thing actually has fairly big error bars, but it's the best estimate they have based on probable composition.

*(1.63^3, 1.63 being the best number I could find for the radius relative to Earth's)

They have 1.6 times the radius and about 5 times the mass of a normal human so it should suit them perfectly.

The correct term is "satellite".

You'll never accrete enough mass to be a TRUE feminist.

Sure. Do you prefer: "stop shaming me for not conforming to your stereotype of what an SJW should look like!", "your discriminatory desire to move people you dislike to another planet makes you WORSE THAN HITLER!" or "this entire discussion ignores the American privilege of having access to a space program that has successfully sent people to space!"

So what if successive administrations have underfunded NASA to the point where it can't carry out manned missions any more, let alone lift a 7 ton "body positive" feminist into orbit.  And so what if two thirds of all youngsters enrolling in college are now female, we still need to defund NASA and use the remaining money for more women-only scholarships

It's a perfect way to showcase your ample belly AND your leftist self-awareness at the same time!

Fuck you would want to be short to have an 'ample belly' and weigh 130 lbs. In fact you'd need to be about 4 foot. Is the talk of huge fat women turning anyone else on?

Burgers I would never have anything less than well done, as much as I like my steak medium-rare. Granted, that only applies when I'm cooking the burgers myself--if I go anywhere to buy a burger, the store won't ask because they'd get sued if a customer contracted something from an undercooked burger.

Anything less or more then medium-rare and you're asking for trouble.  Burgers should always be well-done as it's a mix, not a slab of meat.
Title: Re: Very earthlike planet found by NASA
Post by: Zygarde on August 01, 2015, 04:37:13 pm
Well if we're gonna go down this path I prefer my steaks medium rare not too cooked not to red. While burgers I generally go well done since intestinal parasites and salmonella are a thing.  Also on the topic of the planet I think it's interesting I'm noticing that we are discovering more and more earth like planets which is a strange development to say the least.
