Planets stay in space with out falling because thire is NO gravity in space. The earth pulls the moon that he hole solar system stick together. So it will never fall out of space because thire is no end to space as we know.

Will the sun explode?

The sun is an averaged size star so it doesn't explode. Instead it reheats and expands so earth will be vaporized and inside the sun! Oh yeah and don't freak out it's going to happen in 5 billion years. Plenty of time to get that degree and a good job, and to raise a family. DON'T worry you will be dead or very old.

How many galixies are there?

Your inquiry is definitely in the minds of many scientists who are trying to obtain a good estimate for the number of galaxies in the universe. The methods used to achieve such number varies, and therefore, the results would vary, too. Also, as new and improved technology becomes available, astronomers can detect fainter objects that were not seen before. These objects that have come into view will in turn change the estimated number of galaxies.

What is the moon made out of?

The moon is made of composed of rock and soil, like the earth.And there some are similarities.There is no water on the moon.But the nature of the rocks
