The problem is that some of these objects are so dark and small that they're not discovered until a few days before their close approach or possible impact. Hopefully more student and citizen scientists will get involved in asteroid tracking, and we'll be able to find an Earth killer early and pull it out of it's orbit with the gravity tractor.KRoyMauinoreply@blogger.comtag:blogger.com,1999:blog-3163493865891948082.post-81323098665062956402012-06-15T05:08:54.817+02:002012-06-15T05:08:54.817+02:00One thing that I miss in all these NEO predictions...One thing that I miss in all these NEO predictions and data are velocities and directions. To make it simple so even an astronomer can understand if you are travelling in two parallel trains each with 100 kmph velocity then their relative speed is 0. If on the other hand if you travel in opposite direction then their relative speed is 200 kmph. If they travel tangent or at an angle then things get even more complicated.<br /><br />So if a planetoid travels parallel to earth's orbit it doesnt matter it would alight<br />om earths surface like a papillon on a flower. On the other hand if ....etc.<br /><br />It gets of course a lot more complicted yet as we are not in a static Descartian plane or even three dimensions but in a<br />four dimensional matrix with the three + time. <br /><br />At any rate one would need to know not just the trajectory of the asteroid but also of the Earth. What is the velocity of the Earth in space a known figure and the same for the NEO. <br /><br />Their meeting may be explosive or <br />harmless as two tropical fish kissing.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3163493865891948082.post-59539830089478326822012-06-14T20:04:43.958+02:002012-06-14T20:04:43.958+02:00Does anyone know if you have to be a paying member...Does anyone know if you have to be a paying member of Slooh to be able to view the webcast of this event?Rayzor Raynoreply@blogger.comtag:blogger.com,1999:blog-3163493865891948082.post-72822337719833083032012-06-14T15:49:08.853+02:002012-06-14T15:49:08.853+02:00Only shows that we still have very limited knowled...Only shows that we still have very limited knowledge of space's dangers heading this way. In this case, I don't see what could of been done to stop this rock and the impact would of been a major event, possibly with catastrophic damage/consequences.
