The awesomeness of the universe is simply beyond all human comprehension.
Travelling at the same speed as the fastest object ever created by man - Helios 2 - at a constant speed of 150,000 mph (240,000 km/hr) – it would take 19,000 years to travel the mere 4.2 light years to the nearest star/solar system, Proxima Centauri.
What would happen to a spacecraft if a piece of space debris the size of a tennis ball hit it at that speed?
Nice animation in this:
