How far away is 2004 DW?
2004 DW is at about 45 AU away from us, more distant than Pluto and Neptune, which are both at about 30 AU. 1 AU is an “Astronomical Unit” and is equal to the distance between the Earth and the Sun, about 150 million kilometers. So 2004 DW is about 7 billion kilometers from us. At walking speed (if you could walk in space), it would take you about 150,000 years to get there. Going at the speed the Space Shuttle orbits the earth, it would take about 30 years to get there. It takes light 6 hours to get there from the sun.
