The planet's average temperature is minus 353 F (minus 214 C). But despite being the most distant planet, it is not the coldest.
Neptune: Minus 330°F (-200°C) Dwarf Planet Pluto: Minus 375°F (-225°C) This graphic shows the mean temperatures of various destinations in our solar system.
The temperatures, pressures, and materials that characterize this planet are most likely too extreme, and volatile for organisms to adapt to. Size and Distance With an equatorial diameter of 30,775 miles (49,528 kilometers), Neptune is about four times wider than Earth.
Neptune Facts. Average temperature: -201°C (-331°F) where atmospheric pressure equals sea level on Earth Average distance from Sun: 4,495 million kilometers (2,793 million miles), or 30 times farther from the Sun than Earth Diameter: 49,528 kilometers (30,775 miles), Neptune is 3.9 times wider than Earth
The average global temperature on Neptune unexpectedly fluctuated during a recent 17-year period, according to a new study published by the American Astronomical Society in The Planetary Science Journal.
At its core, Neptune reaches temperatures of up to 7273 K (7000 °C; 12632 °F), which is comparable to the surface of the Sun. The huge temperature differences between Neptune’s center and...
Neptune has an average temperature of -214 degrees Celsius;-353 degrees. Wind speeds blowing westward on the equator reach up to 2,160 kilometers or 1.324 miles per hour, nearly a supersonic flow. Most winds travel retrograde to the rotation of the planet they are 5 times stronger than the strongest winds recorded on Earth, breaking the sound ...
Neptune is the most distant planet from the Sun, with temperatures that plunge down to 55 Kelvin, or -218 degrees Celsius.
Distance from the Sun: Neptune is the eighth planet from the Sun. It orbits at an average distance of 2.8 billion miles (4.5 billion km), thirty times farther than Earth.
