Those of you planning for outer space travel in the future can opt for Neptune. Provided that our spacecraft are sophisticated to travel near the speed of light, Neptune sure has its own unique qualities to attract prospective travelers. Being the farthest planet from our Sun, it is also the densest of the 4 gas giants.

Neptune-Earth ComparisonOne question that gets asked a lot is, since Neptune is a gas (or ice) giant, can you theoretically free-fall into the spatial center and stay afloat. The answer is no, because Neptune has a tiny (slightly smaller than Earth) nickel-iron core. Even if there wasn’t a core, any organism would be frozen and poisoned to death by the methane, if not by gravity itself.

However, those of you interested in landscapes and scenery during travel expeditions will have a treat witnessing the methane cloud patterns on the outer limits of its atmosphere. Wind in the Great Dark Spot can surpass 2100 kph (580 m/s), which is almost as fast as a bullet from the muzzle of a machine gun.

Neptune WeatherI previously mentioned that it’ll be cold in Neptune’s atmosphere, but that is only 1/4 true. The outermost layer (thermosphere) is actually 477 degrees Celsius, enough to melt some metals.

If a visual-gazing vacation isn’t for you, you may also opt for landing on one of the future space stations on Neptune’s largest moon, Triton.
