Mercury an Image with Four Views premium poster
A Museum Quality Poster of Mercury an image with Four Views for sale by Brandywine General Store. Mercury is the smallest planet in the solar system, just a little larger than Earth's moon, and the closest to the sun, making an annual trip around Old Sol in 88 days. Mercury's daytime temperature can reach up to 840 degrees Fahrenheit but since there is not much atmosphere on the planet to hold in the heat, at night the temp plummets to minus 275 degrees. This is the largest swing in temperature of any planet in the solar system. Picture #62a
