What does it mean when the Moon is getting closer?
A supermoon happens when the full moon coincides with the moon’s closest approach to Earth in its orbit. Supermoons make the moon appear a little brighter and closer than normal, although the difference is hard to spot with the naked eye.
Does the Moon get closer to Earth sometimes?
In between, only part of the Moon’s surface reflects sunlight, giving it different phases, as you can see in the diagram below. What’s more, the Moon’s orbit around the Earth isn’t perfectly circular – it’s a very slightly squashed ellipse. This that means sometimes the Moon is closer to the Earth than at other times.
What causes a supermoon?
A supermoon occurs when the Moon’s orbit is closest (perigee) to Earth at the same time the Moon is full. When a full moon appears at perigee it is slightly brighter and larger than a regular full moon – and that’s where we get a “supermoon.
Is China going to the moon?

What would happen if the Moon was closer to the Earth?
The difference between low tide and high tide would be higher, and large tidal waves, depending on the distance of the Moon, would probably cause devastating floods. Finally, if the Moon was closer to the Earth, the gravitational pull would not only affect the waters of our planet, but it could also cause severe earthquakes and volcanic eruptions.
Could a closer moon mean higher tides?
But higher ocean tides wouldn’t be the only result of a closer moon. The moon also has a tidal effect on Earth’s land, Comins said.
How much harder does the Earth pull on you than the Moon?
Right now, the center of the Earth is roughly 6,400 kilometers below you, and the Moon’s center is about 380,000 kilometers above you (actually that can vary depending on where the Moon is in its orbit, but let’s ignore that). Take the ratio and square it, and you see that the Earth pulls on you 3,500 times harder just because it’s closer.
How close is one side of the Earth to the Moon?
But if we bring the Moon in really close, suddenly one side of the Earth is a lot closer to the Moon than the other: The Earth’s near side is 2,158 kilometers from the Moon’s center, and the far side is nearly 15,000 kilometers away.
