  5. Facts About Mercury | Closest Planet to The Sun - Star Walk

    https://starwalk.space/en/news/facts-about-mercury-all-you-need-to-know

    The temperature of Mercury’s surface varies more than on any other planet in our Solar System. It can range from −173 °C (−280 °F) at night to 427 °C (800 °F) during the day. This happens because the smallest planet has almost no atmosphere to trap heat, and it quickly loses the energy received from the Sun during the daytime.
