At first, the skin turns red in the area of the infection, and a tender lump develops. After four to seven days, the lump starts turning white as pus collects under the skin. If the infection spreads to the deeper tissues of the skin, then it becomes an abscess or furuncle.
The International Space Station cruises at about 17,500 mph. The International Space Station has an average elevation of about 220 miles when orbiting Earth. Every hour and a half, the International Space Station completes an orbit around Earth.
Of course it depends on how fast the object is traveling. In one of the NASA Space Shuttles, about 76,526 earth years (38,263 earth years one way). 1 light-year is 5.8 trillion miles and the maximum speed of a NASA Space Shuttle is 17,500 miles per hour. The fastest unmanned space craft traveled 157,000 mph. At that rate, there and back would take only 8,500 earth years. So if you were a Mesopotamian farmer in 6,500 BC, you'd be getting home right about now.
