Earth is about 80 times the volume than the Moon, but both are about the same age. The Moon is the fifth largest natural satellite in the Solar System.Īt 3,475 km in diameter, the Moon is much smaller than the major moons of Jupiter and Saturn.It passed within 5995 km of the surface of the Moon before going into orbit around the Sun. This was a Soviet craft, which was launched from the USSR. The first spacecraft to reach the Moon was Luna 1 in 1959.Scientists think the Moon has a molten core, just like Earth. Lunar astronauts used seismographs on their visits to the Moon, and found that small moonquakes occurred several kilometres beneath the surface, causing ruptures and cracks. These are caused by the gravitational pull of the Earth. The lack of atmosphere means no sound can be heard on the Moon, and the sky always appears black. This means that the surface of the Moon is unprotected from cosmic rays, meteorites and solar winds, and has huge temperature variations. Since then the Moon has only be visited by unmanned vehicles. The first man to set foot on the Moon in 1969 was Neil Armstrong on the Apollo 11 mission, while the last man to walk on the Moon in 1972 was Gene Cernan on the Apollo 17 mission. The Moon has only been walked on by 12 people all American men.This is why the lunar astronauts could leap and bound so high in the air. The Moon has much weaker gravity than Earth, due to its smaller mass, so you would weigh about one sixth (16.5%) of your weight on Earth. A person would weigh much less on the Moon.By the time that happens, the Moon will be taking around 47 days to orbit the Earth instead of the current 27.3 days. It is estimated that it will continue to do so for around 50 billion years. The Moon is moving approximately 3.8 cm away from our planet every year. The Moon is drifting away from the Earth.There are two bulges in the Earth due to the gravitational pull that the Moon exerts one on the side facing the Moon, and the other on the opposite side that faces away from the Moon, The bulges move around the oceans as the Earth rotates, causing high and low tides around the globe. The rise and fall of the tides on Earth is caused by the Moon.The side facing away from Earth has only been seen by the human eye from spacecraft. This is because the Moon rotates around on its own axis in exactly the same time it takes to orbit the Earth, meaning the same side is always facing the Earth. In reality both sides of the Moon see the same amount of sunlight however only one face of the Moon is ever seen from Earth.
The RIAA hasn’t updated that count in over 21 years, and with hundreds of weeks spent on the Billboard 200 since then, it’s likely that between sales and streams, Pink Floyd is owed a few more platinum plaques sometime soon.Moon size compared to the Earth Facts about the Moon The set has now been certified 15-times platinum for selling at least 15 million copies in the United States alone, though the total figure is probably higher.
1 in countries all around the world (including the U.S.) and it has become a classic in the decades since. The Dark Side of the Moon was released in 1973, and it didn’t take long to become an international blockbuster. Legend has spent exactly 625 weeks somewhere on the list, which is still 325 fewer spins than the rock outfit’s release. While that collection is a massive success (one of the biggest ever), it is still years behind Pink Floyd’s greatest accomplishment when it comes to the number of frames spent on the list. The second-longest-charting title in Billboard 200 history is Bob Marley and the Wailers’ greatest hits compilation Legend, which, like The Dark Side of the Moon, continues to perform well enough most weeks to appear somewhere on the chart.
