Vitalis Jackson posted:This isn't necessarily so, for several reasons. The existence of this planet--let's call in Melancholia--was actually postulated based upon certain orbital characteristics of trans-Neptunian objects. It was noted that these objects seemed to have shared points of perihelion relative to the planets. This was unlikely to occur without outside influence, and appears to be nonrandom. The perihelion of Melancholia is supposed to be outside of the orbits of the inner planets. the model of formation for the solar system that we rely on at the moment predicts that a 5th gas giant was ejected from its orbit early on. it could be we've just found where it went could also be something we picked up from another passing star. a neighbor star passes through the oort cloud every 10 million years or so

if we know what all the planets are doing now and the laws of physics at that scale are all deterministic and time reversable just put in the data points and run it backwards and it will tell you how many planets got made in the beginning

naem posted:It's just that we've known the orbits of all the planets since like the 1500's I'm pretty sure someone would have noticed the effects of an extra giant magnet out there Uranus was discovered in 1781. Neptune was discovered in 1846. Pluto wasn't discovered until 1930. And the existence of this potential new planet is being inferred by its gravitational effects on other objects. So someone has noticed the effects of an "extra giant magnet" out there.

I thought the regular 'poo poo being throw at us' cycle was due to us dipping above and below the galactic plane? Even crazy far out, wouldn't something that large make the sun or other planets wobble even slightly?

Second Sun posted:I thought the regular 'poo poo being throw at us' cycle was due to us dipping above and below the galactic plane? There's a theory that the Earth is traversing the galactic plane regularly, because at the time that seemed like the best explanation. If there's a sizable body interacting with the Oort cloud, that's an even better explanation. Instead of assuming we hit clouds of debris in a huge universe randomly, this theory already knows where the debris is, and now possibly we know how it's being interacted with. Possibly.

It's at least 10 times as far away as Neptune, so it gets 1/100th of the sunlight, and reflects 1/10000th. And it moves so little it was basically still in the same place when we started seriously looking at that area of space 30ish years ago.

Ah, so we won't find it until we map the whole sky once a decade for a century and a computer finally picks up the movement.

gently caress, it's not even halfway through the orbit it started when we developed agriculture. That's how big and slow this theoretical orbit is. e- it's ~1/3 of the way around

Huge compared to us, even Jupiter is tiny for us to spot at that distance. I mean, this is a light year away, roundabouts. 10 Earth masses is a relatively small planet, not only in our neighborhood but among discovered exoplanets as well. The planetary average is far larger, or so it seems. e- this may be because of how difficult it is to spot exoplanets, the larger ones will of course be easier to see

Dang, that's pretty far out there. Aside from long-period comets, Sedna is the most distant object in the solar system that we know about. On the off chance it exists, this thing is going to be really hard to find.

I have an irrational fear that all our space flights and orbital maneuvers are stealing kinetic energy from the planets/moons (this is true) but my fear is that in like 200 years when/if spaceflight is a common thing we'll gently caress up the mechanics of the solar system to the point that we'll cause major catastrophes (like planets colliding or something). I know rationally that it would require like trillions and trillions of slingshots and whatever and the sun will be long since nova'd before this is even remotely a concern but still.

Man, reading about all these starts zooming through the galaxy at 700 miles/second makes you scared. First, what thing out there has the power to propel a huge object at those speeds. Second, what if one is headed our way ?! A black hole could be lurking just outside the solar system and we wouldn't know it until it would get close enough to gravitational move stuff in the Oort cloud
