Definition of planet object can be irregular in shape, but beyond that point gravity begins to pull an object towards its own centre of mass until the object collapses into an ellipsoid. (None of the large objects of the Solar System are truly spherical. Many are spheroids, and several, such as the larger moons of Jupiter and Saturn and the dwarf planet , have been further distorted into ellipsoids by rapid rotation or tidal forces, but still in hydrostatic equilibrium.) However, there is no precise point at which an object can be said to have reached hydrostatic equilibrium. As Soter noted in his
OGLE-2014-BLG-0124Lb AUs from it. The two telescopes, OGLE and Spitzer, discovered the planet through gravitational microlensing. This is done by observing when the star passes between Earth and another star. The distance at which the star is seen allows us to observe gravity bending the light and the change of brightness shows the existence of the star. If there is a planet orbiting the star, then the astronomer will also see the same thing twice, which helped astronomers discover OGLE-2014-BLG-0124Lb. OGLE-2014-BLG-0124Lb is known as an exoplanet. These planets are located outside of our solar system. The Kepler telescope has allowed astronomers
