Night sky or good binoculars, the planets appear as discs demonstrating finite size, and it is possible to observe orbiting moons which cast shadows onto the host planet's surface. Venus is the most prominent planet, often called the "morning star" or "evening star" because it is brighter than the stars and often the only "star" visible near sunrise or sunset, depending on its location in its orbit. Mercury, Mars, Jupiter and Saturn are also visible to the naked eye. Earth's Moon is a grey disc in the sky with cratering visible to the naked eye. It spans, depending on its exact location,
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
