Kepler's third law, also known as the law of cycles, refers to all planets orbiting an elliptical orbit with the focus of the sun. The ratio of the cube of the semi-major axis of the elliptical orbit to the square of the period is a constant. Often used for the calculation of elliptical orbits. This software helps users calculate relevant parameters. The software is based on scientific calculation formulas to ensure the accuracy of the calculation results. Come and try it!
