What is the temperature of a habitable planet?
What is the temperature of a habitable planet?
The advanced life that we know about depends upon water, so one condition for the habitable zone is that water can exist in liquid form, so this requires a temperature range between 0°C and 100°C.
Which exoplanet is hottest?
“Hot Jupiters” are massive gas giants that orbit so close to their stars that they are too hot to sustain life. It weighs about three times the mass of Jupiter and boasts surface temperatures of 7,800 degrees Fahrenheit (4,300 degrees Celsius). This makes KELT-9b the hottest exoplanet so far discovered.
What is the temperature of Earth 2021?
As a whole, the July 2021 global surface temperature was the highest for July since global records began in 1880 at 0.93°C (1.67°F) above the 20th-century average of 15.8°C (60.4°F). This value surpassed the previous record set in 2016 (and subsequently matched in 2019 and 2020) by only 0.01°C (0.02°F).
What is the temperature of Earth in Celsius?
NASA has reported that the average temperature of the earth is 15°C. However, extreme temperatures are still possible on Earth. The hottest temperature ever recorded on Earth was measured to be 70.7°C in the Lut Desert of Iran in 2005, and the coldest temperature was -89.2°C in Vostok, Antarctica.
What is the coldest exoplanet?
Planetary characteristics

Is KELT-9b hotter than the sun?
The hot star blasts its nearby planet KELT-9b with massive amounts of radiation, leading to a daylight temperature of 7800 degrees Fahrenheit, hotter that most stars and only 2000 degrees cooler than the sun.
