Q: Will the transit of Venus in a few weeks, be visible at Mars?
Could Oppy (or orbiters) resolve it ??? -------------------- CLA CLL

QUOTE (rogelio @ May 21 2012, 06:24 PM)  I assume that a simultaneous Mercury-Venus transit as seen from Earth is impossible because of the difference in orbital planes? It's not impossible thanks to the precession of the nodes.Hence, Jean Meeus has written (quoted from wikipedia): The simultaneous occurrence of a transit of Mercury and a transit of Venus is extremely rare, and will next occur only in the years 69163 and 224508. The last simultaneous transit occurred in 373173 BC. At this date, we would probably be able to watch by ourself a simultaneous transit from any point in the line sun-mercury-Venus in the solar system, with a portable teleportation equipment.
