It is called a supermoon

Yes, its called a supermoon in the popular terms, but in the technical or scientific terms it called being in the perigee phase of its orbit. When the moon is furthest away from the earth it is in the apogee phase of its orbit.
because theres a time when the moon is closer to the earth called perigee
The moon's distance from Earth varies due to its elliptical orbit. The point where the moon is closest to Earth is called perigee, whereas the farthest point is called apogee. This cyclic change in distance is known as lunar perigee and apogee.
the moon is closer than usual by like 3000 miles =)
The Sun is at the same average distance from both the Earth and the Moon because the Earth-Moon system orbits the sun. However, since the Moon orbits around the Earth, it is sometimes closer to the Sun than is the Earth, and sometimes farther. But the difference is negligible since the Sun is more than 380 times as far from Earth as the Moon.
During a full moon, the moon is opposite the sun with Earth in between, meaning the moon is closer to Earth and further from the sun. This alignment allows the moon to appear fully illuminated from our perspective on Earth.
The moon's average distance to Earth is about 384400km. Its closest approach to earth brings it to 356000km. So it never really is 50000km "closer to the Earth than usual" as long as you are referring to its average distance by that.

The moon is much closer to the Earth than it is to the Sun.

It is closer to the Earth
Mercury is larger than the moon and so is closer in size to Earth than the moon is. It should be noted that Mercury is closer in size to the moon than it is to Earth.
the moon
No, our moon is closer to Earth than the Sun is.
Because at the point of full moon it is about 50 thousand kilometers close to the Earth than usual and therefore appears slightly larger and 30% brighter than usual. This happens because the Moon does not go round the Earth in a perfect circle but in an ellipse. Its orbit therefore takes it away from the Earth at times and at other times it brings it closer to the Earth.

The moon doesn't wobble, if you refer to the movement commonly called 'libration'. That is an apparent motion only, and not a true motion of the moon. There is both east/west libration and north/south libration, and they are independent of one another. Mars is not pushing the moon closer to earth. On average, the moon is very slowly moving farther and farther from the earth, not closer.
