With-out air, there are great temperature differences between the coldest and hottest parts. Mercury days are so long that there are big differences betwcen temperatures on the daylight side and the night side.Mercury was probably created billions of years ago,when big rocks ran into each other...
This is a problem because, by itself, metallic mercury has a very low evaporation temperature and readily turns into a vapor. Here's an interesting fact I learned recently: ever wonder why mercury is the only metal that is a liquid at room temperature? Because it has relatively weak bonds ...
3. changes 【分析】根据“temperature”和“a lot”的提示这里应该填动词的第三人称单数,根据语意 可以推断这里指温度变化大 。 4. longer 【分析】 根据“than”和“One day on Mercury is the same as 59 Earth days. "可知答案。 5.also 【分析 】根据之前的“had a helmet with wings on it"和...
With the exception of the Sun, Mercury is the closest celestial body to Earth. Due to its proximity to the Sun, it experiences极端的温度 fluctuations, with the surface temperature reaching up to 432°C during the day and dropping to as low as -172°C at night.The planet's t...
Mercury can reach 800 °F (430 °C) during the daytime and can get as cold as –300 °F (–180 °C) at night. That’s more than double the coldest temperature ever recorded on Earth! People have known about Mercury for at least 5,000 years. Since it moves faster than the other ...
Based on theoretical analyses and simulations successfully reconstructing Earth's chorus wave properties, we report on possible generation regions of chorus waves in Mercury's magnetosphere. The theoretical analysis for low-temperature-anisotropy electrons shows a clear asymmetric day–night spatial ...
It also experiences the greatest temperature extremes of any planet,ranging from 800 degrees Fahrenheit (426 degrees Celsius) to minus 280 degreesF (minus 173 degrees C) between day and night. Legend has it that Johannes Kepler, who discovered thelaws of planetary motion, never saw Mercury with...
The temperature during the day can reach a scorching 800 degrees Fahrenheit (430 degrees Celsius), but at night, temperatures can plummet as low as minus 290 F (minus 180 C), according to NASA. That fluctuation equals a temperature swing of about 1,100 F (600 C), the largest of any ...
Surface Temperature: highly variable! Night-time temperatures: -173 to -193 degrees C, daytime temperatures of up to 427 degrees C; mean surface temperature = -73 degrees C near the equator. Magnetic Field: weak - 1.1% the strength of earth's and also a magnetic dipole, strong enough to...
Temperature: Due to its eccentric orbit, Mercury has the most extreme temperature of any planet in the solar system. The surface temperature can reach up to 427°C on the day side and drop to -183°C on the night side. Density: Mercury is a dense rocky planet. Its average density is...
