Space


Space is measured by units. (meters,miles, km, etc.) Au, Km, and ly are different ways to measure space or distance. Au (astronomical unit) is the distance between earth and the sun. 1 Au equals 150 million km. One light year equals 63239.2493 Au. You use light years to measure the distance to things in outer space like stars or galaxies.


My body is about 588.8 million miles away from Earth. Since my body is located between mars and Jupiter, the farthest it could be is 588.8 million miles away from Earth because that is how far away Jupiter is. Gailie's spacecraft was originally suppose to take 2 years to go from Earth straight to Jupiter. But it turned out to take 6 years. It would most likely not be possible for humans to make it to the end of the Asteroid belt, but it could be possible to make it to part of the Asteroid belt. So it is possible to make it there.
