Sending an object to another star is still the stuff of science fiction. But some concrete missions could get us at least part way there. These "interstellar precursor missions" include a trip to the solar gravitational lens point at 550 AU from the sun—farther than any artificial object has ever been, including Voyager.
Yes. Always check your units, particularly what the calculator you pull up is using for the center body (Earth in my case). And a side note on that difference, it’s amazing that the velocity for an orbit that far out is still fast. Even with gravity falling off proportionally, even our little sun pulls hard.
