The moon has an elliptical orbit around the Earth. When it is at is perigee (closest position to us) it is 31,000 miles closer then when it is at its apogee (farthest position from us)! This makes the moon look about 14% bigger and 30% brighter.

The moon is not getting closer but further
No. Earth's orbit is stable.
for a 20 earth year period. when Pluto gets closer to the sun than Neptune every 248 earth years.
There is no evidence to suggest the sun is any closer to the earth than it was 10 years ago. The sun is still 92,960,000 miles from Earth.
no
The moon is closer to the Earth then the Sun because the Earth's gravity pulls the moon closer. Also trillions of years ago the Earth was very big. Scientists suspect a meteor hit the Earth and a piece of the Earth broke off. That piece is now called the Moon.
What comes past the Earth every 70-75 years?
Generally, that age is eighteen years in most states.Generally, that age is eighteen years in most states.Generally, that age is eighteen years in most states.Generally, that age is eighteen years in most states.
is when the earth and mars are closer but it takes two years
The Sun's distance to Earth won't change significantly in 20 years.
Yes. Mars comes fairly close to Earth about every 26 months or so as the Earth passes Mars in its orbit. Some approaches are closer than others, due to the fact that both planets are in elliptical orbits. You can see a simulation of Mars and Earth in their orbits at http://www.windows.ucar.edu/tour/link=/mars/mars_orbit.html. When Mars is closer and Earth is farther away from the Sun, as in August 2003, they do get quite close. But they have had such close approaches every few hundred years since the planets formed 4+ billion years ago.
YES. And in a hundred or so million years it will almost touch earth. We will not be here.
