B Simulation: Our Solar System's Hyperbolic Residents

Click For Summary
The discussion centers on a browser simulation that tracks the positions, distances, and speeds of various spacecraft, including Pioneer 10 & 11, Voyager 1 & 2, New Horizons, and ʻOumuamua. Participants ponder whether ʻOumuamua will be considered to have left the solar system upon reaching 121 AU, similar to Voyager 1. There is debate over the definition of the solar system, with some suggesting it extends only to the heliosphere, while others argue it includes the Oort cloud. Questions arise regarding the trajectory of New Horizons and its relation to Sedna. The conversation highlights the complexities of defining boundaries within our solar system.

Thanks for the thread!
Thanks PF_Help_Bot! I feel so much better now.:rolleyes:

Honestly, I didn't expect many replies. I learned a while back that if you want replies, you have to phase it like you're starting a conversation. Perhaps even ask a question. The "Like" option is perfect for threads like this.

I wonder if when 'Oumuamua reaches 121 AU, it will be considered having "left the solar system" like Voyager 1 was. I wonder how Sedna feels about this.

Interesting question. I think the common usage is solar system = heliosphere, but this is only what I've adapted so far. I wouldn't even say V'ger has left the system, as long as it hasn't passed the Oort cloud, and this will still take quite some time. Does anybody know why e.g. NH isn't heading for Sedna?
 
"Pop III stars are thought to be composed entirely of helium and hydrogen with trace amounts of lithium, the ingredients left over after the Big Bang. They formed early on, around 200 million years after the universe began. These stars are extremely rare because they died out long ago, although scientists have hoped that the faint light from these distant, ancient objects would be detectable. Previous Population III candidates have been ruled out because they didn't meet the three main...
