How big is the moon?

Earths moon is the brightest item in our night sky. How big is the moon? The moons mean radius is 1,079.6 miles (1,737.5 kilometers) and the mean diameter is 2,159.2 miles (3,475 km). Compared to Earth, the moon is less than a third the width of our house planet, according to NASA. The moons equatorial circumference is 6,783.5 miles (10,917 km). Initially, the moon may appear rather big, but that is only because it is our closest celestial body– roughly 238,855 miles (384,400 km) away on average. moon stats– Radius: 1,079.6 miles (1,737.5 km)– Diameter: 2,159.2 miles (3,475 km). — Surface location: 14.6 million square miles (38 million square km)– Mass: 7.35 x 1022 kg– Density: 3.34 grams per cubic centimeter (3.34 g/cm3) The moon is a bit more than one-quarter (27 percent) the size of Earth, a much bigger ratio (1:4) than any other planets and their moons. Earths moon is the fifth largest moon in the solar system.” If Earth were the size of a nickel, the moon would have to do with as big as a coffee bean,” according to a declaration from NASA.The moons surface location has to do with 14.6 million square miles (38 million square km), which is less than the total surface area of the continent of Asia (17.2 million square miles or 44.5 million square km). Related: Does the moon rotate?Moon gravitythe, mass and density moons mass is 7.35 x 1022 kg, about 1.2% of Earths mass. Put another way, Earth weighs 81 times more than the moon. The moons density is 3.34 grams per cubic centimeter (3.34 g/cm3). That has to do with 60% of Earths density. The moons gravitational force is just about 16.6 % of Earths gravity which means a person would weigh six times less on the moon than they do in the world. A 45-kilogram individual would weigh 100 pounds. in the world however just 16.6 lbs. on the moon. Long dive events on the lunar surface area would definitely be interesting as a person who can jump up 10 feet on Earth would be able to leap practically 60 feet on the moon.Like many of the planetary system worlds, the moons gravity varies based on its surface features. In 2012, NASAs Gravity Recovery and Interior Laboratory (GRAIL) mission mapped the moons gravity in unprecedented detail.Did you know?The moon is the 2nd densest moon in the solar system; Jupiters moon Io is denser, with 3.53 g/cm3. ” What this map informs us is that more than any other celestial body we know of, the moon wears its gravity on its sleeve,” GRAIL principal private investigator Maria Zuber of the Massachusetts Institute of Technology said in a statement. “When we see a noteworthy modification in the gravity field, we can sync up this modification with surface area topography features such as rilles, mountains or craters.” While the moon is the closest and among the longest studied astronomical objects, researchers continue to press the heavenly body for details.” The moon is the Rosetta Stone by which we understand the rest of the planetary system,” Noah Petro, deputy task researcher for NASAs Lunar Reconnaissance Orbiter (LRO) objective, said in a statement. The moon is a little more than one quarter the size of Earth. The Deep Space Climate Observatory satellite caught the moon and Earth together as the orbit of the satellite crosses the orbital airplane of the moon.

According to the science education website The Nine Planets (they still love Pluto), our moon is the most significant in the planetary system relative to the size of its planet, it is the fifth-biggest overall. Jupiters moon Ganymede is the biggest moon in the planetary system.

Used by astrologer Richard Nolle in 1979, “supermoon” initially referred to a full or new moon that takes place when the moon is within 90 percent of its closest method to Earth.” The main factor why the orbit of the moon is not an ideal circle is that there are a lot of tidal, or gravitational, forces that are pulling on the moon,” Petro informed Space.com, adding that the gravity of the Earth, sun and worlds of our solar system all impact the orbit of the moon. One method to evaluate whether its simply an illusion is to hold your thumb up next to the moon and compare the moons size with your thumbnail. When the moon is higher in the sky, look at it once again; the moon will be the exact same size compared to your thumbnail.Additional resources Looking for more quick moon realities, these educational infographics by ESA have actually got you covered.
