The average distance from Venus to the Sun is about 67 million miles (108 million kilometers), while the average distance from Earth to the Sun is about 93 million miles (150 million kilometers). This means that Venus is closer to the Sun than Earth is.
The orbits of planets in our solar system are elliptical, which means they are not perfect circles but slightly elongated. However, the overall size of the orbit is determined by the semi-major axis, which is the average distance from the planet to the Sun.
In the case of Venus, its average distance from the Sun is smaller than Earth's average distance, resulting in a smaller orbit. This means that Venus completes its orbit around the Sun in a shorter time period compared to Earth. Venus takes approximately 225 Earth days to complete one orbit, while Earth takes about 365.25 days to orbit the Sun.
It's important to clarify that the sizes of orbits are determined by various factors, including the initial conditions of the planetary system, gravitational interactions, and other celestial influences.
