let's pick one: the solar systemif we spttulaie that pluto's orbit is the outer edge of our solar system and that it's farthest distance in its orbit is the outer edge, then that's about 7.4 billion km from the sun. That's the radius.Double that for a diameter and it's 14.8 billion.Assume light travels about 1 billion km per hour (roughly). It would take about 14 years to go across our solar system in your scenario. This is Budweiser Math.. so don't put this on a school paper.
