Kepler 19b, the Earth like planet is doubted to have an invisible world exerting force on it. But no visible evidence is yet found. Kepler's spacecraft traces the details of the planets those pass by. The same spacecraft has found the orbit of Kepler 19b around it's star delays by about 5 minutes. This made the world doubt if there is an other invisible world which is exerting force on this Kepler 19b. This is not all but astronomers named it as Kepler 19c. Astronomer Sarah Ballard of the Harvard-Smithsonian Center for Astrophysics says, "This invisible planet makes itself known by its influence on the planet we can see,". Once found, the things may turn out very crazy, as happened with the Neptune, which has been found by studying the unknown force acted upon the Uranus. Even the gravitational force exerted by this unknown world on the Kepler 19b is also very less, which is leaving us helpless in calculating the mass, at least. Co-author Daniel Fabrycky of the University of California, Santa Cruz says, "Kepler-19c has multiple personalities consistent with our data. For instance, it could be a rocky planet on a circular 5-day orbit, or a gas-giant planet on an oblong 100-day orbit,". I wish this is going to turn out into an amazing piece of study and anyways, Stay glued for more updates :)
