Minimum orbit intersection distance ( Moids)
07/07/07 at 05:23:20
The Lowell observatory keeps track of Asteroids as the come and go .  
Hereunder is a link to what's called the present MOIDS . For each asteroid the Minimum distance to earth and other planets is given in a table. That's what the call MOID ( in Au ) .  
The site covers al lot of bodies , even small ones .
The simulation herunder is a time-frame in which the orbits of 15 bodies are drawn as they possibly come close to earth . Earth is the point in the middle with the orbit of the moon around it .  
For this animation I selected the 15 bodies with the smallest MOID , so the bodies that can come very close ( in a more extended time-frame). Data come from the JPL Database.  
The simulation spans about 15 years ; a screenshot was made every 50 days .  
The width of the picture is 0.5 AU and pixels were on average drawn every 5 days.
