Neptune, the eighth and farthest planet from the sun, has the strongest winds in the solar system. At high altitudes speeds can exceed 1,100 mph. That is 1.5 times faster than the speed of sound. In 1989, NASA’s Voyager 2 spacecraft made the first and only close-up observations of Neptune.
How strong is Neptune’s winds?
The highest winds observed in the solar system have been measured on Neptune with speeds near 1,200 mph near the “older” Great Dark Spot. The equatorial regions of Neptune possess average wind speeds of over 700 mph, which is faster than the speed of sound here on Earth.
Why does Neptune have the strongest winds?
The cold temperatures might decrease the friction in the system, so that winds can get going fast on Neptune. … In fact, Neptune radiates 2.61 times as much energy as it receives from the Sun. This is enough heat to help drive the fastest winds in the Solar System.
What is Neptune best known for?
More than 30 times as far from the Sun as Earth, Neptune is the only planet in our solar system not visible to the naked eye and the first predicted by mathematics before its discovery. In 2011 Neptune completed its first 165-year orbit since its discovery in 1846.
Why is Neptune so windy?
What they found was a planet covered in dense, methane-rich clouds that whipped around Neptune at more than 1,000 miles per hour, making it the windiest spot in the solar system.
What is the 5 dwarf planets?
As the authority on the naming and classification of celestial objects, the International Astronomical Union officially recognizes five dwarf planets in the solar system:
- Pluto.
- Eris.
- Ceres.
- Makemake.
- Haumea.

What is the most violent planet?
0.015% 0.007% 3.5% 64% Page 2 Venus is the most dangerous planet in the solar system: its surface is at 393°C, hot enough to melt lead. It’s even hotter than the planet Mercury, which is closest to the Sun. Venus’ atmosphere is acidic and thick.
Can a human live on Neptune?
The answer is that we couldn’t live on the planet Neptune for a few reasons. It’s far too cold, there’s no oxygen and it’s primarily made up of ice! So, it’s not going to be suitable for colonization by humans any time soon, even though it is within our solar system.
Does it rain diamonds on Neptune?
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. … Beyond the lingering mystery of the diamond rain, there’s a big loss in our failure to study Uranus and Neptune inside and out.
What planet has the strongest wind?
Winds on Neptune travel faster than the speed of sound. Neptune, the eighth and farthest planet from the sun, has the strongest winds in the solar system. At high altitudes speeds can exceed 1,100 mph.
How can we live on Neptune?
To find life on Neptune, the planet would need to have a source of energy that bacterial life can exploit, as well as a standing source of liquid water. At its surface, the temperature of Neptune dips down to 55 Kelvin. That’s very cold, and there’s no way liquid water could exist.

Is Neptune all water?
Structure. Neptune is one of two ice giants in the outer solar system (the other is Uranus). Most (80 percent or more) of the planet’s mass is made up of a hot dense fluid of “icy” materials—water, methane and ammonia—above a small, rocky core.
How cold is it in Neptune?
The average temperature on Neptune is about minus 200 degrees Celsius (minus 392 degrees Fahrenheit). Neptune, the farthest known planet of our solar system, is located about 30 times farther away from the sun than Earth is.
Does Neptune have a lot of storms?
Neptune has the wildest and strangest weather in the entire Solar System. It has huge storms with extremely high winds. Its atmosphere has dark spots which come and go, and bright cirrus-like clouds which change rapidly. Neptune has an average temperature of -353 Fahrenheit (-214 Celsius).
Why is Neptune so cold?
Most agree that Neptune is the coldest planet due to its proximity to the sun. The sun produces most of the heat that helps planets regulate their temperatures. Neptune is so far away from the sun that it does not get enough heat to melt the ice caps that form on the planet.
