Discovery

The planet was discovered as a result of examinations of data from the previously discovered exoplanet : Kepler-19b

Kepler-19b

Kepler-19b is a planet in the orbit of star Kepler-19. The planet has an orbital period of 9.3 days, with an estimated radius of roughly 2.2 Earth radii, and mass less than 20.3 Earth masses .-References:*http://arxiv.org/pdf/1109.1561v1...

. Timing variations in the orbital period

Orbital period

The orbital period is the time taken for a given object to make one complete orbit about another object.When mentioned without further qualification in astronomy this refers to the sidereal period of an astronomical object, which is calculated with respect to the stars.There are several kinds of...

of the first planet necessitated gravitational forces to be acting upon the planet, resulting from an additional body in the vicinity, acting to cause a variation of transition of five minutes per orbit.
