Next to the moon, planet Venus appears most brightly and visibly to Earth. (Because of Venus’s proximity to the Sun, it gets more intense light). Venus gets closer to Earth than any other planet, presenting the same side at each closest approach at inferior conjunction. Hypothetical Venetians would see Earth as full on the other side of the Sun whenever Venus appear full also on the other side of the Sun.
Even though the sun is much more larger and has stronger overall gravity than the moon, the moon is much closer to the earth so that is the reason why its gravitational gradient is stronger than that of the sun
