Mind Blowing Facts About Mercury
Mercury is slightly larger than our Moon, with a circumference of 15,329 kilometres around its equator. It has a radius of 2,440 kilometres, which is the distance from the core's centre to the surface. Mercury is roughly 2.6 times the size of Earth.Temperatures of around 430°C, hot enough to melt lead, scorch Mercury's sun-facing side. Without a substantial atmosphere to distribute heat away from areas facing the Sun, the planet's slow rotation results in significant temperature differences between its dark and light sides. The side facing away cools to about -180°C. Despite the intense heat that the planet experiences as it rotates, areas that are permanently shaded, such as some polar craters, may contain ice deposits. Temperature swings from day to night make it impossible for life as we know it to thrive on Mercury. Mercury, despite being the closest planet to the Sun, is not the hottest planet in the solar system. Venus's dense atmosphere causes a greenhouse effect, resulting in higher temperatures.
