Here's why:
* Temperature is a measure of the average kinetic energy of molecules in a substance. Planets are massive and have a lot of material, making it very difficult for their temperatures to change rapidly.
* Planets have atmospheres: Atmospheres act as insulators, helping to regulate temperature changes.
* Distance from the sun: While planets further from the sun are colder, their temperatures change slowly over time, not within a single day.
So, where did this idea come from?
It's likely a misunderstanding or a fictional concept. Perhaps you've encountered a story or video game where a planet has extreme temperature fluctuations.
