Question

Write about synodic and sidereal month

Answer 1

However, because the Earth is constantly moving along its orbit about the Sun, the Moon must travel slightly more than 360° to get from one new moon to the next. Thus, the synodic month, or lunar month, is longer than the sidereal month. A sidereal monthlasts 27.322 days, while a synodic month lasts 29.531 days.
