A view of the distance of 'Oumuamua from each of the Inner Planets as it rounded the sun, reached perihelion and then sped away again.
Mars was just about as far away as it could possibly have been from 'Oumuamua.
'Oumuamua came very close to Earth (around 0.16 au).
It came no closer to Mercury and Venus than would be expected of 'Oumuamua's low perihelion (~ 0.25 au) orbit.
