How far exactly is Neptune from the Sun?
Size and Distance From an average distance of 2.8 billion miles (4.5 billion kilometers), Neptune is 30 astronomical units away from the Sun.
How many years would it take to get to Neptune?
12 years Neptune (Voyager) Want to go to Neptune? It'll take 12 years. Fortunately, there's no good reason anyone would want to go there.
Is Neptune closer than the Sun?
Neptune is at a distance of 2.77 billion miles (4.46 billion km) when it is closest to the Sun and 2.82 billion miles (4.54 billion km) away when it is farthest from the Sun.
Is Neptune all water?
Unlike the gas giants Jupiter and Saturn, Uranus and Neptune are rich in water. Most of that water is likely in the form of ice, but there may also be a liquid layer as well.
Does it rain on Neptune?
We're learning more and more about the mysterious ice giants in our solar system. Scientists have recreated conditions on Neptune and Uranus in a lab at Stanford's SLAC National Accelerator Laboratory.
What if you fell into Neptune?

Does it rain diamonds on Neptune?
The postdoctoral research at NASA's Goddard Space Flight Center explained that the high amount of methane in both Uranus and Neptune is the key factor why it rains diamonds on the two planets.
Can you walk on Neptune?
But temperatures at this region would be thousands of degrees; hot enough to melt rock. And the pressure from the weight of all the atmosphere would be crushing. In short, there is simply no way one could stand on the “surface of Neptune”, let alone walk around on it.
What planet is the coldest?
Uranus The coldest planet in our solar system on record goes to Uranus which is closer to the Sun and 'only' about 20 times further away from the Sun than the Earth is. The lowest temperature recorded there was minus 224 degrees Celsius.
Can you swim in Neptune?
Being an ice giant, there is no water on the surface of Neptune. Having a surface temperature of −201 oC any water on Neptune will be frozen. Extraterrestrial liquid water is believed to be beneath the ice surfaces of the Jovian moons Europa and Ganymede.
Which planet is full of diamonds?
For centuries, astronomers have been fascinated by Saturn. After all, she has been hailed as the precious jewel of our solar system, one of the most beautiful planets. And while her rings have mesmerised us for centuries, it is even more amazing to realise that it quite literally rains diamonds out there!
What planet that rains diamonds?
Deep within Neptune and Uranus, it rains diamonds—or so astronomers and physicists have suspected for nearly 40 years. The outer planets of our Solar System are hard to study, however. Only a single space mission, Voyager 2, has flown by to reveal some of their secrets, so diamond rain has remained only a hypothesis.
What planet can humans live on?
Kepler-62e and Kepler-62f are thought capable of hosting life. The planet Kepler-69c is located about 2,700 light-years from Earth in the constellation Cygnus. This is an illustration of the planet, which is the smallest yet found to orbit in the habitable zone of a sun-like star.
How much gold is in space?
Well, at current market prices, 16 Psyche contain enough gold and other precious metals to be worth roughly $700 quintillion, which is enough to give every single human being on this planet a private fortune of nearly a hundred billion bucks.
What planet is hottest?
Venus Because of this, Venus is the hottest planet in the solar system. The surface of Venus is approximately 465°C! Fourth from the Sun, after Earth, is Mars.
Why is Neptune so hot?
"The extra heat source on Neptune (and Jupiter and Saturn) is largely due to gravitational contraction," said Joshua Tollefson, also of the University of California, Berkeley.
Does Diamond Rain on Neptune?
On Neptune and Uranus, it rains diamonds! While this is a striking reminder of how ordinary diamonds are in the greater scheme of this universe, it also sheds light on how elusive most terrains remain for humanity. Uranus and Neptune are both ice giants and also share a similar blue tint in terms of their appearance.
What would happen if a human went to Neptune?

What planet does it rain acid?
Venus But if that doesn't sound painful enough, rain on Venus is made up of extremely corrosive sulphuric acid, which would severely burn any interstellar traveller's skin.
What planet does it rain glass?
HD 189733b The weather on HD 189733b is deadly. The winds, composed of silicate particles, blow up to 8,700 kilometres per hour (5,400 mph). Observations of this planet have also found evidence that it rains molten glass, horizontally.
Is there another Earth with humans?
The Kepler space telescope identified the exoplanet, and its discovery was announced by NASA on 23 July 2015….Kepler-452b.

How cold is space?
In fact, it doesn't actually have a temperature at all. Temperature is a measurement of the speed at which particles are moving, and heat is how much energy the particles of an object have. So in a truly empty region space, there would be no particles and radiation, meaning there's also no temperature.
What planet is coldest?
Uranus The coldest planet in our solar system on record goes to Uranus which is closer to the Sun and 'only' about 20 times further away from the Sun than the Earth is. The lowest temperature recorded there was minus 224 degrees Celsius.
What is Earth’s twin planet?
Venus Venus is often called "Earth's twin" because they're similar in size and structure, but Venus has extreme surface heat and a dense, toxic atmosphere.
What planet has tornadoes?
Rather unusually, Mercury has magnetic 'tornadoes' that were observed by NASA's Mercury MESSENGER during a flyby in 2008. The tornadoes are twisted bundles of magnetic fields that connect Mercury's magnetic field to Space.
What planet is made of diamonds?
In 2012, Yale University scientists published a study announcing the identification of a planet rich in diamonds. Called 55 Cancri e, the planet is "possibly covered in diamond, rather than water and granite," scientists explained at the time. The exoplanet is twice the size of Earth but has eight times its mass.
What planet can we live on besides Earth?
Kepler-62e and Kepler-62f are thought capable of hosting life. The planet Kepler-69c is located about 2,700 light-years from Earth in the constellation Cygnus. This is an illustration of the planet, which is the smallest yet found to orbit in the habitable zone of a sun-like star.
Which planet is most like Earth?
Venus and Mars are the most like Earth, but in different ways. In terms of size, average density, mass, and surface gravity, Venus is very similar to Earth. But Mars is the planet that is most similar to Earth in other ways.
How dark is space?
How dark does space get? If you get away from city lights and look up, the sky between the stars appears very dark indeed. Above the Earth's atmosphere, outer space dims even further, fading to an inky pitch-black. And yet even there, space isn't absolutely black.
