Answer

Brief Explanations:

Neptune and Pluto were identified as planets due to their movement relative to the fixed - stars in the sky. Neptune's discovery was based on perturbations in Uranus' orbit, and it was located by observing its motion. Pluto was also discovered by observing its movement across the sky. They were not discovered within 10 years of each other (Neptune in 1846, Pluto in 1930), not recognized as planets because of orbiting objects, and not discovered using a sextant (more modern telescopes and calculations were involved).

Answer:

They were both identified as planets by virtue of their movement in the sky.
