What's It Like On Mercury?

The video explores the conditions on Mercury, the closest planet to the Sun. It discusses Mercury's orbit, rotation, and size, comparing it to Earth and the Moon. The surface features, including craters and the exosphere, are examined. Despite its proximity to the Sun, Mercury is not the hottest planet due to its thin atmosphere, leading to extreme temperature variations. The presence of ice in shadowed craters is also noted. The video explains Mercury's gravity and density, highlighting its large metallic core. Finally, viewers are encouraged to continue exploring space with SciShow.
