| 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.
Although Mercury is the closest planet to the sun, it is only the second hottest planet after Venus. Venus gets hotter as the thick carbon Dioxide atmosphere holds the heat moâ¦re effectively, while Mercury has no atmosphere. Surface temperatures on Venus average 735 Kelvin or 460 Â°C. Venus has the highest surface temperature. Although Mercury is closer, Venus holds the suns heat in much more efficiently with its thick Carbon Dioxide atmosphere.
