Mercury gets more sun, yet Venus stays hotter

Original: 🔥 NEW: # Mercury orbits closest to the # Sun and receives nearly four times the # energy per unit area that Venus does,

Mercury, the closest planet to the Sun, receives nearly four times the solar energy per unit area that Venus does and is the least reflective planet in the Solar System. Despite this, Venus holds a steady surface temperature of about 462°C both day and night, a fact being shared widely in science discussions.

Why now: The striking contrast between Mercury's solar exposure and Venus's higher temperature is a popular space science talking point.
