Planets - Calculate Orbit (Year) Length

Calculator for the duration of the planetary orbits around the Sun, in hours, days and years and compared to each other. Planets orbit a star, in our solar system, this star is the Sun. The orbit shapes are ellipses. The time for one orbit is called year. The further away a planet is from its star, the longer the orbit takes and the longer is the year of that planet.

Round to    decimal places.

Please enter one value, the other values will be calculated.
Days (d) refers to the 24 hours of a day on Earth. A year (y) is calculated as exactly 365.25 days.

Example: the Mars year is almost as long as 1.9 Earth years, Pluto needs 248 years for one orbit around the Sun.
