There is the problem: 1672, measurements of the astronomical unit: from 66 to 138 Mkm 1675, estimation of the time needed bt light: from 7 mn to 11 mn So, the estimation of the speed of light is from 100 000 km/s to 330 000 km/s that's in the order of 180 000 km/s, but the estimation is only good in the order It's not really a measurement -- Oncle Dom _________ http://perso.orange.fr/oncle.dom/
