How does the orbit work?

Could you please explain, in simple terms, how exactly does the orbit of a celestial body work? How is it that planets, moons, and other space objects maintain their paths around larger bodies like stars and planets? What forces are at play here, and how do they interact to create such predictable and stable patterns in the vastness of space? I'm particularly curious about the role of gravity and how it influences the orbit of these celestial bodies. Thank you in advance for shedding some light on this fascinating topic!
