Nonetheless, when there are a number of planets in the system that orbit comparatively shut to each other and have ample mass, orbital stability evaluation allows one to constrain the utmost mass of these planets. The radial-velocity technique can be used to affirm findings made by the transit method. When each methods are used in combination, then the planet’s true mass might be estimated. Though radial velocity of the star solely provides a planet’s minimum mass, alternative therapy for kidney disease if the planet’s spectral lines will be distinguished from the star’s spectral lines then the radial velocity of the
