First applied by astrologer Richard Nolle in 1979, 'supermoon' originally referred to a new or full moon that occurs when the moon is within 90 percent of its closest approach to Earth. When a full moon coincides with perigee, we get a supermoon, which appears 14 percent larger and 30 percent brighter than usual. Perigee is the term for when the moon is closest to Earth. Super moonД«ecause the moon's orbit is not circular, it is sometimes closer than at other times.

'The moon is the Rosetta Stone by which we understand the rest of the solar system,' Noah Petro, deputy project scientist for NASA's Lunar Reconnaissance Orbiter (LRO) mission, said in a statement.

While the moon is the closest and one of the longest studied astronomical objects, scientists continue to press the celestial body for details. 'When we see a notable change in the gravity field, we can sync up this change with surface topography features such as craters, rilles or mountains.' 'What this map tells us is that more than any other celestial body we know of, the moon wears its gravity on its sleeve,' GRAIL principle investigator Maria Zuber of the Massachusetts Institute of Technology said in a statement. In 2012, NASA's Gravity Recovery and Interior Laboratory (GRAIL) mission mapped the moon's gravity in unprecedented detail. Like most of the solar system worlds, the moon's gravity varies based on its surface features. A person who can jump up 10 feet on Earth would be able to jump almost 60 feet on the moon. A 45-kilogram person would weigh 100 lbs. The moon's gravitational force is only about 16.6 percent of Earth's gravity. The moon is the second densest moon in the solar system Jupiter's moon Io is denser, with 3.53 g/cm 3.

That is about 60 percent of Earth's density. The moon's density is 3.34 grams per cubic centimeter (3.34 g/cm 3). Put another way, Earth weighs 81 times more than the moon. The moon's mass is 7.35 x 10 22 kg, about 1.2 percent of Earth's mass.
