The planet was previously proposed in 2012 when reports of its host star recorded drops in its luminosity varying from 0.2% to 1.3%, which indicated a possible planetary companion rapidly disintegrating. In 2015, the planetary nature of the cause of the dips was finally verified. It is expected to disintegrate in about 40–400 million years.

Calculations of mass loss rates show that the planet probably had a mass slightly smaller than Mercury in size when it first formed, since the calculations show that planets with masses larger than 7% the Earth's barely lose any mass over billion year time-scales.

The mass of Kepler-1520b is unknown; however, modeling of the mass loss rate of the planet indicates that it cannot be more massive than about 2% of the mass of the Earth (less than double the mass of the Moon). According to calculations, it may have lost 70% of its original mass; we may be currently
