| Cool Cosmos. Since Mercury has hardly any atmosphere, it does not have weather like storms, clouds, winds or rain. Its surface temperature can reach 801 Fahrenheit during the day (because it is so close to the Sun) and can drop to -279 Fahrenheit at night (because there is no atmosphere to trap the daytime heat). Cool Cosmos is an IPAC website. Based on Government Sponsored Research NAS7-03001 and NNN12AA01C.
Without an atmosphere, Mercury loses a great deal of heat into space, rather than sharing with its night side. The hottest planet, incidentally, is Venus, the second body from the sun. Venus has a thick atmosphere that blankets the planet, keeping its temperature at an average of 864 F (462 C).rbiting between 28 and 43 million miles (46 and 70 million kilometers) from the sun, Mercury, also the smallest planet, feels the brunt of the solar rays.
