Neptune is the eighth and farthest planet from the Sun by far
It was discovered by mathematical calculations. Only once has a spacecraft visited the orbit of this distant icy giant - it was Voyager 2 in 1989.
🔵 Neptune's atmosphere is mostly hydrogen and helium, as well as hydrocarbons, nitrogen and methane, which is the cause of the planet's blue color.
