The temperature, reaction rate ... the Solar System is home to the giant planets and their ... of Venus allowed astronomers to calculate the average Earth–Sun ...
According to the IAU's explicit count, there are eight planets in the Solar System; four terrestrial planets (Mercury, Venus, Earth, and Mars) and four giant planets, which can be divided further into two gas giants (Jupiter and Saturn) and two ice giants (Uranus and Neptune). When excluding the Sun, the four giant planets account for more than ...
The planet has an average estimated surface temperature only 50°F warmer than Earth’s. “Thrillingly, this planet is the closest Earth-sized and temperature planet we know,” Thomas Wilson ...
On the dark side of the planet, temperatures average 110 K. [15] [82] The intensity of sunlight on Mercury's surface ranges between 4.59 and 10.61 times the solar constant (1,370 W·m −2). [83] Although daylight temperatures at the surface of Mercury are generally extremely high, observations strongly suggest that ice (frozen water) exists on ...
[83] [e] The average temperature of the corona and solar wind is about 1,000,000–2,000,000 K; however, in the hottest regions it is 8,000,000–20,000,000 K. [84] Although no complete theory yet exists to account for the temperature of the corona, at least some of its heat is known to be from magnetic reconnection.
The record is all but certainly the warmest temperature the planet has seen in at least 100,000 years.
It is in the inner edge of its planetary system's habitable zone, giving it an estimated average surface temperature of 68 °C (154 °F). [119] Studies that have attempted to estimate the number of terrestrial planets within the circumstellar habitable zone tend to reflect the availability of scientific data.
