I say we catch that sucker, tow it into our neck of the woods as a second moon, and use it as a space port. Are there a million problems with this proposal? Yes. But would it be totally rad to do this? Also yes.

With such a huge difference between peri- and aphelion, won't it be moving extremely fast when it's nearby?

It’s pronounced your-uh-ness by pretty much everyone (or your-ah-noose if your going by the greek god and not the Latin copy/paste.)

Leave it to HN to explain grammar, some history and a bit of etymology in response to a childish joke comment. And, that's why this place is great.

Hope I can contribute, because this is actually very interesting. According to this [1], the most common American pronunciation was closer to "Your anus" (accent on the A in anus) until 1986, when a space probe was flying by and news casters thought weeks of that would get too "giggly", so they deliberately started pronouncing it "Urine us" (accent on the first syllable).

Is it a comety composition? Crash it into mars for some ocean and atmosphere?

I keep hoping we'll get lucky in my lifetime and something big like that will just hit Mars on it's own.

It would be a hell of a world to go from "desert" to "so we've got all these new oceans to name and also you can't breathe it but ground level pressure is one atmosphere".

I'm not sure how the mechanics of a 200 km wide comety like object hitting Mars at ~25 km/s would work out, but I'm reasonably certain that it would result in a major resurfacing event. I'd venture that the majority of the gasses would retain escape velocity following impact.

Well, since we’re just assuming we could meaningfully change it’s trajectory we might as well also assume we could slow it down!

It's not a rogue planet, that implies Interstellar. This is an object with a very long orbit that takes it out to he Oort cloud but still - a permanent resident of the solar system. It's basically just an exceptionally large comet. It's not Melancholia.

Love that movie

It made me so nauseous I had to stagger out of the cinema.

Thank you. That was amusing to read and I never actually realized there was so much about the pronunciation, I've heard a few different ones. but I always took it for regional dialect differences not something done intentionally. I may have sounded sarcastic, but I was genuinely serious, I really do enjoy the interesting factoids spawned by sometimes the most innocuous comments on HN. HN really does have a lot of people knowledgeable about a huge range of things.

Love the creativity! That said, the moon stabilized earth’s rotation angle, giving us the seasons, and it also drives huge chunks of life ecosystems and weather with the tides. So adding a second body in rotation to Earth with such superpowers would muck with a lot of stuff along the way. Maybe put it around Mars instead?

The diameter of this asteroid is estimated to be ~160 km, which is 21.7 times less than Moon with d=3474 km. Assuming similar density, the mass of the new asteroid is 10000 less than Moon and it's unlikely to affect much.
