Revolution

The video tutorial explains the concept of revolution in astronomy, focusing on how planets and moons orbit around larger celestial bodies. It details Earth's revolution around the Sun, which defines our year, and the Moon's revolution around Earth, which defines our month. The tutorial also discusses how Earth's revolution affects seasons and compares the revolutions of different planets, like Mercury and Neptune. An exercise is provided to calculate age in Mercury years.
