* The length of Earth's orbit around the Sun: This is approximately 365.25 days, which is why we have leap years to account for the extra quarter day.
* The length of an object's orbit around Earth: This depends on the object's distance from Earth and its speed. For example, the International Space Station orbits Earth every 90 minutes, while the Moon takes about 27.3 days.
Please provide more context about the specific orbit you are asking about so I can give you a more accurate answer.
