It took the gravity of mighty Jupiter to bend the Ulysses spacecraft's trajectory " downward " and away from this plane of the ecliptic, sending it off where no craft had ever traveled.

It doesn't look like it is " furthest " from Neptune in the plane of the ecliptic at that time, but like that's when it is " crossing " the ecliptic.
43.
The asteroid was not discovered sooner because it spends most of its time beyond the orbit of Mars, has a large orbital inclination, and spends most of its time well below the plane of the ecliptic.

The surprises about cosmic-ray intensities, he said, demonstrated the scientific value of sending a spacecraft out of the plane of the ecliptic for what he called a look at the solar system in three dimensions.
45.
Twice per year, in mid-November and in late January, the corridor lines up with the plane of the ecliptic, causing sunlight to fill the entire corridor, events that are celebrated by students and staff.
46.
While scientists ponder what they have already learned, Ulysses is cruising northward and will recross the plane of the ecliptic in February and begin a comparable four-month survey of the Sun's northern polar region in June.
47.
Since the Earth also lies on the plane of the ecliptic, it sometimes passes between the sun and the moon, causing lunar eclipses; hence the origin of " ecliptic, " the place where eclipses happen.
48.
It follows that aliens who wanted to find other civilizations to talk to would find our planet by the transit method too . . . which suggests that SETI should preferentially search for radio signals along the plane of the ecliptic.
49.
Planetary precession ( an advance ) is due to the small angle between the gravitational force of the other planets on Earth and its orbital plane ( the ecliptic ), causing the plane of the ecliptic to shift slightly relative to inertial space.
50.
Orbiting the Sun at a distance of 2.7 3.4 AU once every 5 years and 4 months, the asteroid's path is nearly coplanar to the plane of the ecliptic with an orbital inclination of less than 2 degrees.
