45 Things That Are Much Bigger or Smaller Than We Thought

Mercury, the Solar System’s smallest and nearest planet to the Sun, has a cratered surface due to its minimal atmosphere and lack of geological activities. This highlights the Sun’s immense size and power.

Experiencing extreme temperatures, Mercury’s surface heats up to 800 degrees Fahrenheit by day and plummets to -290 degrees at night. Despite its proximity to the Sun, Venus surpasses it in heat due to its thick, heat-trapping atmosphere.
