In the spirit of historic astronomical endeavors, we invited school groupsacross the globe to collaborate in a solar distance measurement using the rareJune 5/6th transit of Venus. In total, we recruited 19 school groups spreadover 6 continents and 10 countries to participate in our Hetu'u Global Network.Applying the methods of French astronomer Joseph-Nicolas Delisle, we usedindividual second and third Venus-Sun contact times to calculate the distanceto the Sun. Ten of the sites in our network had amiable weather; 8 of whichmeasured second contact and 5 of which measured third contact leading toconsistent solar distance measurements of 152+/-30 million km and 163+/-30million km respectively. The distance to the Sun at the time of the transit was152.25 million km; therefore, our measurements are also consistent within1sigma of the known value. The goal of our international school group networkwas to inspire the next generation of scientists using the excitement andaccessibility of a rare astronomical event. In the process, we connectedhundreds of participating students representing a diverse, multi-cultural groupwith differing political, economic, and racial backgrounds.
