The Voyager probes travel too slowly for my liking…

When talking about astronomical distances, the most appropriate unit is the “light-year” (distance travelled by light in a vacuum in one year).

 

While reading an article about the Voyager spacecraft (launched 1977, 36 years ago) I found out one of them is “0.002 light years” away from Earth. I don’t know about you but that doesn’t mean much to me, so I plugged it into Wolfram Alpha, which is the best thing since sliced bread.

 

Conversion to “light-days” (non-standard) allows me to appreciate the distances a little better. For reference, the distance to the nearest star to our own (Sol).
