Mass : 1.69 +-0.41*M(earth) Radius:1.20 +-0.09*R(earth ) Star-Planet Seperation : ~0.01AU. A simulation on the future trajectory of Kepler 78b. Kepler 78b was discovered to be ~0.01 AU to its Star, way too close for planet formation here Transition state, orbit will decay

Mass : 1.69+-0.41*M(earth) Radius:1.20+-0.09*R(earth) Star-Planet Seperation: ~0.01AU A simulation on the future trajectory of Kepler 78b • Kepler 78b was discovered to be ~0.01 AU to its Star, way too close for planet formation here • Transition state, orbit will decay • A simplified planet-Star system • All in real SI units • Runge-Kutta Method -Weihan Liu
