Neptune's vastly greater distance from the Sun more than makes up for its much lower mass in the 'tug of war' between star and planet. Huh. That's interesting. Does Neptune's SOI have a larger apparent diameter from Earth? Quote Link to comment Share on other sites More sharing options...
kinnison Posted July 4, 2016 Share Posted July 4, 2016 575,000 miles from Jupiter, 12 hours to insertion. Now inside the orbit of Ganymede, and velocity is starting to noticeably increase. From 37k Miles/hr it should peak at 129k miles an hour at perihelion and get as close as 2800 miles from Jupiter Quote Link to comment Share on other sites More sharing options...

Imagine the size of the SOI of the proposed ninth planet! It would get much smaller near perihelion, of course, but still! Quote Link to comment Share on other sites More sharing options...

That's over 150.9 Astronomical Units! Spoiler I got that value using the predicted semi major axis of 700 AU, a predicted mass of 10 Earth masses, and the mass of the Sun in solar masses.

max_creative Posted July 4, 2016 Share Posted July 4, 2016 (edited) JUNO ARRIVAL!!! WOO YEAH!!! I think that text is a little bit on the big size though... Edited July 4, 2016 by Vanamonde Ease up on the font size there, Sparky. Quote Link to comment Share on other sites More sharing options...
Kelderek Posted July 5, 2016 Share Posted July 5, 2016 I just saw that the spacecraft will have a 35 minute long orbital insertion burn tonight. That gives me a whole new perspective thinking of my 8 or 10 minute LV-N burns in KSP, lol. Quote Link to comment Share on other sites More sharing options...
Astrofox Posted July 5, 2016 Share Posted July 5, 2016 So, today's the day that we finally see whether our spacecraft will be inserted into orbit around the Giant Planet Jupiter. Coverage on this will begin at 10:30 EST (7:30 PM PST, 2:30AM UTC), and the insertion will be in about an hour and thirty minutes (as of typing this up). It's first page stuff: https://www.nasa.gov/ Quote Link to comment Share on other sites More sharing options...

Astrofox Posted July 5, 2016 Share Posted July 5, 2016 The only thing unfortunate about this amazing mission is that tons of conspiracy theorists will post tons of videos trying to prove that it's fake . Oh well, we'll get them to learn someday. Quote Link to comment Share on other sites More sharing options...

SuperFastJellyfish Posted July 5, 2016 Share Posted July 5, 2016 Looking at the number of miles to Jupiter in NASA's Eyes tick by is astounding. I've played KSP for years and it still amazes me how fast spacecraft move. Quote Link to comment Share on other sites More sharing options...
Ultimate Steve Posted July 5, 2016 Share Posted July 5, 2016 Okay. This is the ninth mission to Jupiter. Five minutes to go. 1. Pioneer 10 flyby. 2. Pioneer 11 flyby. 3. Voyager flyby 4. Voyager 2 flyby 5. Ulyssses flyby. 6. Gallileo Orbiter. 7. Cassini flyby 8. New Horizons flyby. 9. Juno orbit. That makes Juno the second ever spacecraft to orbit Jupiter!
