when do sailor neptune and uranus come in
Sailor Uranus Haruka is a stubborn, protective individual, as well as strong-willed, capable, charming, and occasionally even daring. She is formally introduced in the third story arc, although she appears in silhouette alongside Sailor Neptune in the final episode of Sailor Moon R. She is the tallest of the Sailor Soldiers at 5'8", followed by Sailor Pluto at 5'6".
Discovery of Neptune The planet Neptune was mathematically predicted before it was directly observed. With a prediction by Urbain Le Verrier, telescopic observations confirming the existence of a major planet were made on the night of September 23–24, 1846,[1] at the Berlin Observatory, by astronomer Johann Gottfried Galle (assisted by Heinrich Louis d'Arrest), working from Le Verrier's calculations. It was a sensational moment of 19th century science and dramatic confirmation of Newtonian gravitational theory. In François Arago's apt phrase, Le Verrier had discovered a planet "with the point of his pen".
