I was curious about its motion relative to the earth, and looked for a solar system simulation on the web. I learned Venus is getting closer to Earth in its orbit on a crude simulator, and then found this preview of a coming simulator on Reddit. Looks amazing. The comments mention several other competitors which I haven't checked out yet.<br />http://www.reddit.com/r/technology/comments/s9tc6/update_my_room_matean_unemployed_video_game/N.Normalnoreply@blogger.comtag:blogger.com,1999:blog-4912713243046142041.post-40569045911678117702012-04-03T14:57:05.507-05:002012-04-03T14:57:05.507-05:00That's an interesting question.

I can't give a definitive answer to it, but my guess is most likely yes, it will eventually run out.<br /><br />Here is a relevant excerpt from an interview with a NASA astronomer:<br /><br />"Terry A. Hurford: Most of the material does fall back under the surface of Enceladus, but about 10% of it escapes [...]. <br />One of the thoughts about the south polar region is that it is depressed a little bit from the rest of the moon. So, maybe that might be an indication of how much material has actually been lost from that part of the moon."<br /><br />Full interview is here: http://www.nature.com/nature/podcast/v447/n7142/nature-2007-05-17.htmlSebannoreply@blogger.comtag:blogger.com,1999:blog-4912713243046142041.post-53215485705138711542012-04-03T12:21:46.076-05:002012-04-03T12:21:46.076-05:00Wow.

Or does the gravity of Enceladus pull it back in? ???Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4912713243046142041.post-16939107077559839072012-04-02T12:23:14.277-05:002012-04-02T12:23:14.277-05:00Great picture!

Saturn and its moons are simply fascinating.<br /><br />One of my favorite astronomy pictures (currently my desktop wallpaper) shows Saturn lit from behind:<br />http://upload.wikimedia.org/wikipedia/commons/b/ba/Saturn_eclipse.jpg<br /><br />You can clearly see the E ring (the outermost one), which is believed to be constituted primarily of particles coming from the constant eruptions on Enceladus.<br /><br />As an added bonus, the little dot that's visible on the left just inside the G ring is the Earth!<br /><br />(more info: http://photojournal.jpl.nasa.gov/catalog/PIA08329)Sebannoreply@blogger.com
