Anything from picoseconds to millennia.
Saturn completes one orbit around the Sun in 29.4571 years.
Assuming that the speed stays constant, the higher the altitude, the more time is taken to complete one orbit. In this situation, the altitude is directly proportional to the time taken; as one increases, so does the other.
Mercury takes 87.969 days to orbit the sun.
One complete round of Earth on its orbit around the Sun is called a "year." It takes approximately 365.25 days for Earth to complete one orbit.
It is called a year because it takes that much time to complete one orbit of the sun.
Neptune. It was discovered in 1846, and will not complete its first orbit around the Sun since then until next year, giving it an orbit duration of roughly 165 years.
It takes Venus about 224.7 "Earth days" to complete one orbit.
The time it takes to complete one orbit varies depending on the object and its orbital path. For example, the International Space Station orbits Earth approximately every 90 minutes, while Mars takes about 687 Earth days to complete one orbit around the Sun.
Earth takes a lot longer to make one complete order around the sun than Mercury does. The time required for Mercury to make one orbit is equal to 88 Earth days (whereas one orbit for Earth is about 365 Earth days).
Mars takes about 687 Earth days to orbit the Sun once.
A year. Each planet in a solar system has a year of different length, equal to the time it takes for one complete orbit around its sun.
It takes one year for us to complete one orbit.
