Getting pics and spectrum of the object would be enough.
Though having this as a 'extra-solar' mission means they could effectively use it as a was to do some of the same studies the Voyagers have done beyond Pluto.
No, it would get slung out to Jupiter more for directional assist, with the speed being from dropping back to do a near 180-swing around the sun to get the momentum needed.
The first Falcon 9 to take human's to orbit has had it's last flight, most likely, due to tipping over on the drone ship in high winds and heavy seas while returning to port.
So the Super-Heavy kinda dug a hole under the launch pad during lift-off.
It's not wrecking the pad, but it does show more flame-diversion equipment and a more robust launch pad floor are needed.
It's only 160 ft wide; if they think it is going to impact, they can redirect it like they did with the DART mission.
And if that doesn't work, it's small enough blowing it into chunks that will burn up as they come in not that hard.
