(Phys.org)—Located approximately 1530 light years from the soil in the constellation of Cygnus,Kepler-36 is a sun-like star orbited by two known alien worlds. The inner planet, designated Kepler-36b is a so-called "super-soil, and " as it is larger than our domestic planet but smaller than Neptune; the larger Kepler-36c,resembling the solar system's outermost planet, is described as a "mini-Neptune." What is unusual approximately this planetary system is that these two exoworlds have very close orbits, and separated only by 0.013 astronomical units (AU)—five times the soil-moon distance. In a new research paper published online on Feb. 9,Princeton scientists are trying to determine physical conditions and understand the evolution process of this curious, distant system.
