Imagine, if you will, a year that stretches on for 165 Earth years. A planet where a single orbit around the sun takes nearly a lifetime. This, my friends, is Neptune. The farthest known planet from the sun in our solar system, Neptune's year is a testament to the immense scale of the cosmos. Neptune, named after the Roman god of the sea, is a silent Sentinel in the outer reaches of our solar system. It's a world of extreme winds and temperatures so cold that methane a gas on Earth exists as ice. Remember, while our years fly by, Neptune is still on the same orbit it started in the late 1800s. So, next time you feel time slipping away, spare a thought for Neptune where a year is a very, very long time indeed.
