The Inner Planets of the Solar System - Volume One: Mercury and Venus- Solar System Series

The video explores the characteristics of Mercury and Venus. Mercury, the smallest planet, is closest to the sun and lacks an atmosphere, leading to extreme temperature fluctuations. It has a long day and short year due to its slow rotation and fast orbit. Venus, similar in size to Earth, rotates slowly in the opposite direction, resulting in a day longer than its year. It has a dense carbon dioxide atmosphere, making it the hottest planet with high surface pressure and active volcanoes.
