Interesting article. I did not know that ‘Oumuamua passed so close to the Sun.

Question: What prevented ‘Oumuamua from being drawn into the Sun's gravitational field and impacting the Sun? - 01-09-2019, 04:36 PMnot_Fritz_ArgelanderRe: SWaB: "this was the time of Oumuamua's life"
High angular momentum does the trick. The gravitational potential energy is proportional to 1/r (so the force is inverse r squared) and attractive. But determining the radius the object can get to needs including the "effective" potential energy due to angular momentum conservation. THAT is proportional to 1/r^2 (so the force is inverse r cubed) and

**repulsive.**It's what keeps all the planets in their orbits not getting swallowed by the Sun.

But it was good throw :Banane44: Bullseye ;-)

Thanks nFA. It makes sense now.
