Here's a link to an article about the planet that revolves around the Sun in 248 years:

     (( *Neptune: the Distant Ice Giant** Neptune )) 

is the eighth planet in our solar system and the furthest from the Sun. It takes Neptune 248 Earth-years to complete one orbit around the Sun. It was discovered in 1846 and it was the very first planet that could be found by mathematical calculations rather than direct observation. **Orbital Characteristics** Neptune is nearly 30 times further away from the Sun (about 4.5 billion km) than Earth. Its orbit is elliptical with its closest point (perihelion), which is about 2.77 billion miles, and its furthest point (aphelion), which measures about 4.55 billion km (2.83 million miles). *Revolution and Rotation** Neptune has a long orbital period, which means its seasons can last many decades. Neptune's year is equal to 164.79 Earth-years. Neptune is relatively close, but rotates fairly quickly. A day lasts about 16 hours, 6 minutes.

           (( Composition and atmosphere ))

Neptune has a similar composition to Uranus and is classified as a ice giant. Its main components are hydrogen, methane, and helium. Neptune's blue color is due to the methane in its atmosphere. Moons and Rings Neptune is known to have 14 moons. The largest, Triton was discovered only weeks after Neptune's discovery. Triton orbits Neptune retrogradely, which is unusual among large moons. This suggests that Triton may have been captured in Neptune’s gravity. Neptune has also faint rings that were discovered by the Voyager 2 in 1984. **Exploration** Voyager 2 was the only spacecraft to have visited Neptune, which was in 1989. Voyager 2 has provided the most detailed data and images on Neptune, including its dynamic atmosphere, Great Dark Spot, (a massive storm), its moons, and rings.

                    (( **Conclusion** ))

Neptune continues to fascinate scientists and astronomers with its unique characteristics and long orbital period. Its mysterious and distant nature makes it an intriguing subject for further exploration and study, providing insights into the outer reaches our solar system.
