In 2017, astronomers discovered 'Oumuamua - the first definitive interstellar visitor to our solar system. But definitive evidence of space rocks that don't just visit but join our solar system is a little more elusive.

I remember Hyakutake. I was 8 years old, and my parents drove us a couple of hours out of Denver into the mountains to see it. I remember it was basically just a very dim, fuzzy dot you could only really see if you didn't look directly at it. But learning now that Hyakutake might have been an interstellar object makes that memory that much more profound.

I'm happy that Comet Hyakutake is considered a possible visitor to our Solar system as this was the first comet I recall seeing that looked like a "proper" comet. I recall watching Hyakutake visibly move against the background stars in '96, a warmup for Hale-Bopp.

Within seconds it was brighter than the sun, and as it moved across the heavens-at first in utter silence-it left behind it a churning column of dust and smoke.*

It's not that simple. Even if it came directly from one of the closest stars (which it didn't), that's still thousands of years ago. Stars are constantly moving and affecting each other's orbits, and these rocks have probably been travelling through interstellar space for millions of years. It's not really possible to extrapolate backwards on those sorts of timescales.

They are traveling faster than the solar system's escape velocity. Which leaves only 2 options.

It seems that the odds of an interstellar object entering our solar system is so low you’d expect it to nearly never happen. It might be like shooting a bullet from Mt. Rainier with a really powerful gun, but hitting a target on Maui. It might even be harder than that. But gaps between solar systems are so vast that odds are, an interstellar object would simply fly through space for eons without hitting any solar system.

@user-iq6cc3df3l 10 днів тому
I believe that an object in a solar system can only go hyperbolic if: A. It has its own propulsion, or B. It’s interstellar. I’m no physicist but I believe a hyperbolic trajectory only happens if an object’s speed is high enough to achieve escape velocity. In this case I guess the Sun would be the candidate for that object to revolve around but a hyperbolic orbit comes in flat and leaves flat, usually gone to the next solar system, wherever that might be.
@TheMoonRover 5 годин тому
Gravitational assists are also a thing. If an object passes too close to a much larger object (like a planet) its velocity (speed and direction) is going to be significantly altered. Plenty of space probes have exploited that to reduce the fuel requirement, but the larger planets could just as easily boost a random comet onto an escape trajectory.
