As a result of Pluto's reclassification, which planet became the outermost planet in the solar system?

Explanation:
Pluto’s reclassification as a dwarf planet removed it from the list of official planets, so the line of planets ends with Neptune. The term “outermost planet” refers to the planet with the greatest average distance from the Sun, not the farthest point in its orbit. Neptune sits about 30 astronomical units from the Sun on average, and there are no other recognized planets farther out. Pluto’s orbit can bring it closer to the Sun than Neptune at times, but that doesn’t change Neptune’s status as the outermost planet among the eight.
