Planets and Their Characteristics

The video explains the definition of a planet according to the International Astronomical Union, which includes orbiting the Sun, having sufficient mass for a nearly round shape, and clearing its orbital path. It then provides details about the eight planets in our solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, highlighting their unique characteristics such as size, atmosphere, and orbital periods.
