DNA

Explanation:

If all of the DNA in the cells of a human body was unraveled and laid end to end, it would stretch out to #1.20xx10^9# kilometers. The moon is about #4.0xx10^5# kilometers away from the earth, so the DNA would stretch to the moon and back 1500 times. In fact, it would stretch to the sun and back about 4 times. The sun is #1.5xx10^8# kilometers away from the earth.
