Astronomy Curious?

It takes a little over 8 minutes for light from the sun to reach each.  So, in other words, if the sun were to suddenly disappear, those of us living on earth would not know it for 8 minutes or so...

It would take about 332 minutes for light to reach the planet pluto from earth or almost 6 hours.  So, if the planet Pluto were to disappear, those of us living on earth would not know it for almost 6 hours.

Proxima Centauri, the closest star to the Solar System. Part of a triple star system called Alpha Centauri; Proxima is 4.2 light years from Earth.

So, if the Earth disappeared, Proxima Centauri, would not know it for a little over 4 hours...
