An orbit around the Sun is the path that a celestial body, like a planet, takes as it moves through space. This movement is caused by the gravitational pull of the Sun, which keeps the planets in their specific paths. Each planet has a unique orbit, with Earth taking about 365 days to complete one full revolution. The shape of an orbit is usually an ellipse, which means it is slightly oval rather than a perfect circle. The distance from the Sun varies during the orbit, affecting the amount of sunlight and heat a planet receives, which influences its climate and seasons.
