The next 4chan Q&A/PMQ session will be held on Sunday, November 18th at 8:00PM EST.

I'm also taking questions/comments/feedback/random musings via e-mail at moot@4chan.org and on AIM at MOOTCHAT. Feel free to drop me a line or say hi!

Enjoying your first week on 4chan?
>>
>>5258242 (OP)
orphaned planets sound badass
they just fly the fuck around goin wherever the fuck they want
ain't no orbit gonna hold them back
ain't no star gonna tie them down
>>
Wait, is it not more humorous that the op is apparently implying that anyone in this thread is ever going to another planet with a star?

That's not out of the scope of science is it?
Imagine telling people you were going to broadcast images on lcd screens through the air powered by electricity 500 years ago.

im a proud black planet who dont need no gas giant. i gots six moons and a seventh one is collectin inerta in my southwest quadrant, and aint nobody gonna tell me i cant feed my babbies. and dont you even think about snatchin me and my darlins up in your gravity well, honey. that theres slavery and id demand compensation in form of light rays
>>
>>5260402
...but the closest exoplanet would take like 180,000 years or something like that for us to get too traveling at 40,000 mph. i think we see the big picture exponentially better than we did 500 years ago and we understand enough to know thats never happening

sooo... what else? the ion engines they are designing would still take 45-50 thousand years. are you workin on some inter-stellar space ship in your basement or somethin?

What planets don't have stars in their skies? You mean without a sun?
>>
>>5260566
rogue planets. they form around a star but got ejected from their original orbit
>>
>>5260568
Or planets that formed in the absence of a star, it is possible.
>>
>>5260568
>>5260566
and OP's post didn't say no stars in there skies, "starless" meaning not orbiting a star. the Sun is the star we orbit, other stars aren't referred to as suns except on dumbed down discovery channel specials or shit like that
>>
>>5260568
How does the ejection happen?

What is and isn't orbit? Does any body have two suns like in movies?

Not this >>5260508 retard but.....

Bitches don't know bout my pusher plate. Alpha Centauri Bb in 10 years using 70s tech.
>>
Why would I want to go to a rogue planet? They would be cold as balls.
>>
>>5260609
Orbits are inherently unstable. The planets did not form in there current positions. These tugs can cause planets to be ejected from there solar system by other planets. We probably had over 20 planets early in the solar system s formation. We know every planet still in the solar system has collided with another planet sized body at least once.

The answer to your other question is yes planets can form in binary star systems. Our closest exoplanet neighbour we know of Alpha Centauri Bb is in a triple star system
>>
What are the odds that space is actually rather full of unadopted planets?
>>
>>5260617
but that technology never panned out
the ion engine is far more likely to work
so we're still lookin at 45,000 years of travel time
>>
>>5260637
overwhelmingly high
>>
>>5260637
Nearly 100 %

Ejected planets are a normal part of solar system formation.
>>
>>5260652
>never panned out
It was never even tested. The theory is sound, someone just needs to make it happen.
>>
>>5260625
depends. a planets sized brown dwarf near the end of its life cycle could theoretically still be burning enough fuel to keep it a comfy 80-90 degrees. sure, technically its a star, but on the other hand jupiter just hasn't accrued enough mass to become a star yet
>>
>>5260652
The tech works. It is just a little dirty to use in atmosphere. When and if these things get built it will be in space where to fallout from hundreds of nukes won't give everyone cancer.
>>
>>5260660
>>5260656

"never panned out" wasn't the right way to word it. getting this fucked out into space far enough away to start its engine is a logistical nightmare
>>
>>5260661

Everything worth doing is a logistical nightmare.
>>
>>5260661
Not really. Using the right kind of bomblets the fallout could be minimized even when launching from the ground using main engines.

And that's just one option. A medium sized craft could be launched high enough into the atmosphere by shuttle SRBs that when the main engine kicks in, the fallout would be diluted so much it wouldn't be an issue.

And of course the bomb-drive is just ONE type of nuclear engine. Granted that it's very efficient, but there are dozens of different schemes, some of which provide a high specific impulse without venting radioactives outside the drive housing.
