Solar analog 5533K, but is much younger than the sun, at 1.9 billion years old. Another such example would be HIP 11915, which has a planetary system containing a Jupiter-like planet orbiting at a similar distance that the planet Jupiter does in the Solar System. To strengthen the similarities, the star is class G5V, has a temperature of 5750 K, has a sun-like mass and radius, and is only 500 million years younger than the Sun. As such, the habitable zone would extend in the same area as the zone in the Solar System, around 1 AU. This would allow an Earth-like
Entropic gravity surface area would be given by: From algebraic substitution of these into the above relations, one derives from first principles Newton's law of universal gravitation: Entropic gravity, as proposed by Verlinde in his original article, reproduces the Einstein field equations and, in a Newtonian approximation, a 1/r potential for gravitational forces. Since its results do not differ from Newtonian gravity except in regions of extremely small gravitational fields, testing the theory with earth-based laboratory experiments doesn’t appear feasible. Spacecraft-based experiments performed at Lagrangian points within our solar system would be expensive and challenging. Even so, entropic gravity in its current
