The eighth planet from the sun and the fourth largest, with a diameter almost four times that of Earth. Neptune has a very active weather system with extremely long and powerful storms. It is the coldest planet in the solar system, with an average surface temperature of -330°F (-201°C...
In 2009, NASA's Lunar Reconnaissance Orbiter found craters near the moon's south pole that are always in shadow; temperatures in these craters measured in at a balmy 33 Kelvin (minus 400 degrees Fahrenheit) — colder even than any temperature on distant Neptune.2009年，美国宇航局的月球勘测轨道...
Analysis of the preliminary results from the Voyager mission to the Neptune system has provided the scientific community with several methods by which the temperature of Neptune's satellite Triton may be determined. If the 37.5 K surface temperature reported by several Voyager investigations is correct...
We investigate the effects of these mechanisms on the gradual temporal changes of Neptune's stratospheric temperature and conclude that local variations in stratospheric temperature during each event, on the order of 20K, are dominated by viscous dissipation of inertia-gravity waves....
(288 degrees Fahrenheit); and the temperature on Venus, which is almost as hot as the hottest temperature on Mercury, is constant. The outer gas giants — Jupiter, Saturn, Uranus and Neptune — all have surfaces that compare with Mercury at its coldest, but they become warmer deeper inside...
With Dr Tsiaras’s analysis, K2-18b is now the best candidate for a life-supporting exoplanet out there. The temperature on the surface could be about the same as Earth and there could be similar clouds hanging in the sky. 据席亚拉博士分析,K2-18b目前是适宜生命生存的系外行星的最佳候选者...
Question: What is the average temperature on Mercury? Mercury: Mercury is the closest planet to our sun. It circles the sun every 88 days, rather than Earth's orbit of 365 days. The surface of Mercury is rocky and resembles that of Earth's moon. It is a dense planet, but not the ...
The planet’s mean density is similar to that of Neptune, and according to thermal evolution models, it has a H/He-rich envelope constituting 9.0−2.9+2.7% of the total mass. With an equilibrium temperature around 2,000 K, it is unclear how this ‘ultrahot Neptune’ managed to ...
