Answer:
Neptune is a truly fascinating world. But as it is, there is much that people don’t know about it. Perhaps it is because Neptune is the most distant planet from our Sun, or because so few exploratory missions have ventured that far out into our Solar System. But regardless of the reason, Neptune is a gas (and ice) giant that is full of wonder!
This may sound like a pretty simple statement, but it’s actually rather complicated. When it was first discovered by in 1846, Neptune became the most distant planet in the Solar System. But then in 1930, Pluto was discovered, and Neptune became the second-most distant planet. But Pluto’s orbit is very elliptical; and so there are periods when Pluto actually orbits closer to the Sun than Neptune. The last time this happened was in 1979, which lasted until 1999. During that period, Neptune was again the most distant planet.
