Finding inclination of exoplanets I hope that SIM PlanetQuest will find inclination for all or nearly all of the exoplanets as of 2015 2025 Finding inclination is important because we can find the true mass of all or nearly all of the exoplanets Then we can determine the true mass types of planets according to planetary mass type currently a makeup classification By time when is 2015 2025 this classification of planets by mass would exist by BlueEarth working in IAU and have assembly of new makeup classification and release into scientific literature
