[–] shane@feddit.nl 1 point 9 months ago (3 children) Do you though? I mean, a satellite orbiting the sun between the earth and the sun could cast a large shadow, right? permalink fedilink source parent hideshow 6 child comments replies: [–] zalgotext@sh.itjust.works 6 points 9 months ago Not really. Case in point - the Moon. It's absolutely massive, like several orders of magnitude larger than any satellite we've ever launched, and when it happens to line up just right between the Earth and the Sun, the umbra is only like 150km wide. permalink fedilink source parent [–] SpacetimeMachine@lemmy.world 3 points 9 months ago If the sun was a point light source that is accurate. It is not though. You would need an absolutely enormous sat to cast a shadow that would actually affect our weather. Plus you would also need a way to keep it in position as the solar radiation would push it out of position quickly. permalink fedilink source parent [–] balsoft@lemmy.ml 2 points 9 months ago* That's... Not how shadows work... Or orbital mechanics... Or economics... His suggestion, impossible as it is at the current stage of human development, is slightly less impossible than this. permalink fedilink source parent
