The greenhouse effect of Venus' atmosphere makes Venus hotter than Mercury. The result is a “runaway greenhouse effect” that has caused the planet’s temperature to soar to 465°C, hot enough to melt lead. Although Mercury gets the full blast of the Sun's radiation, Venus has a very dense atmosphere that consists predominantly of carbon dioxide which is a greenhouse gas. Even though Venus isn't the closest planet to the sun, it is still the hottest. The extreme temperature of Venus can be attributed to the thick atmosphere it boasts.
