In space you can find a lot of quaint places with abnormal high or low temperature. Or meet the largest meteorite, asteroid, the massive comet, the highest mountain, the Grand canyon and much more. On space records in the Solar system in this article and will be discussed.
Planet with maximum surface temperature
The highest temperature that was recorded on Solar system planets — 464 °C on the planet Venus . Due to the very thick atmosphere it holds heat from the sun and at night the temperature is almost constant day and night. Slightly lower was the recorded temperature on the planet mercury — 430 °C.
The lowest recorded temperature on the surface of the body
