Distance

Space is measured in three different ways: kilometers, Astronomical Units and light years. Each one is very different from the other. A kilometer is a metric unit of measurement equal to 1,000 meters. An Astronomical Unit is equal to 150 million kilometers. A light year is equal to almost 10 trillion kilometers. We use kilometers for walking,running or driving distances. AU is how you measure the distance between Earth and a planet. A light year is the speed of light and is used to count the greatest distances.

Hermes is only about 0.02 AU away from Earth. It is fairly close for an asteroid. It would be about 6 million kilometers and would take 222 years to get there. I think we could only get there if we had an extreme improvement of technology. But as if now could we get there, definitely not.
