The supermoon rises over Beijing on Sunday. The phenomenon, which scientists call a "perigee moon," occurs when the moon is near the horizon and appears larger and brighter than other full moons.
The moon appeared bigger and brighter when it went supermoon on June 23, 2013 — especially when it was seen next to objects on the horizon, such as the helicopter from the original Batman television show at the New Jersey State Fair last year.
