# Talk:Voyager 2

The "encounter" times for Ross 248 and Sirius don't seem to be correct or match the velocity of Voyager 2.
The current text reads:
[T]he spacecraft travels one light-year in about 19,541 years [...] In roughly 42,000 years, Voyager 2 will pass the star Ross 248 (10.30 light-years away from Earth)[...] If undisturbed for 296,000 years, Voyager 2 should pass by the star Sirius (8.6 light-years from Earth)[...]
If the given speed is correct, then Ross 248 would be around 200k years and Sirius a little less than that. Both stars seem to be getting closer to Earth, but surely that won't make that much of a difference?  
Can anyone shed light on this?  Fh1 (talk) 03:40, 28 October 2024 (UTC)

The star's going to Voyager 2 more than Voyager 2's going to the star. Voyager 2's 15 kilometers further from the Sun every second, Ross 248's >77 kilometers closer to the Sun each second and will be 3.048 light-years away 36,500 years from now over 7 light-years closer than it is now.

Thanks for that info. But isn't the Sirius encounter time still wrong: shouldn't it be way _less_ than 200k years, given that it's approaching the Sun? Fh1 (talk) 01:27, 11 December 2024 (UTC)
The scientists got that right too. Sirius is moving several times faster than 5.5 km per second will only get slightly closer to Earth 7.8 vs 8.6 light years and is rather far from the constellation Voyager 2's going toward and is luckily going more sideways than to Earth in almost the perfect direction which will allow it to get as close as 4.3 light years to Sirius.

"10 years of continuous flight and operation at 14:29:00 UTC", etc. seem useless. It's not very notable and the readers can calculate it themselves if they need to; it's trivial to do. Should it be removed? NOTAROBOT1101 (talk) 07:52, 7 October 2025 (UTC)

Yeah, I agree with you; time passing is not an event. If showing how long it's been running for is desirable, it'd make more sense to me to add a column for that instead.

Also agree, the 10 year marks are pointless. – The Grid (talk)  12:52, 7 October 2025 (UTC)
I've removed the "continuous flight" entries in the timetable. As always, feel free to improve it if need be. NOTAROBOT1101 (talk) 15:28, 7 October 2025 (UTC)

French Wikipedia gives additional info : the date when each disabled instrument was switched-off. Wisdood (talk) 12:08, 21 October 2025 (UTC)

the dates are in the "Timeline of travel" table. Artem.G (talk) 12:56, 21 October 2025 (UTC)

Hi all, I haven't edited much before now and was wondering about voyager 2's closest approach to Jupiter. On this article From NASA: https://science.nasa.gov/mission/voyager/voyager-2/ the value is listed at 645,000km (400,785 mi) away from Jupiter, which contradicts the value listed in the source on the referenced JPL article which lists 570,000km. should this value be edited? Any advice would be greatly appreciated.  TedwardTheGreat (talk) 07:34, 10 November 2025 (UTC)

The referred image in this article depicts the Voyager 1 and 2 positions possibly correctly in "PLAN" (which is mentioned in caption also as - Plot 1 is viewed from the north ecliptic pole), but in "FRONT ELEVATION" and in "SIDE" representation, Voyager 1 is shown progressing south of ecliptic plane and Voyager 2 is shown progressing north of ecliptic plane - whereas it should be the reverse if i understand correctly !!! 
So am I missing something here? request if someone could please confirm / clarify - thanks a lot. Jn.mdel (talk) 18:19, 19 November 2025 (UTC)

After adding this discussion topic yesterday, I have messaged the original contributor of this graphic also for review because further noticed that even "Pioneer 10", "Pioneer 11" and "New Horizons" positions also appear to be vertically-flipped in the "FRONT ELEVATION" and in "SIDE" representation in this image - as all these are shown progressing/positioned south of ecliptic plane in this image - whereas if one refer's to NASA's LIVE FEED at https://eyes.nasa.gov/apps/solar-system/#/sc_voyager_1 - then "Voyager 1", "Pioneer 10", "Pioneer 11" and "New Horizons" are progressing/positioned north of ecliptic plane - and "Voyager 2" is progressing south of ecliptic plane.
Hence, to summarise the point - in this image, the galactic centre is somewhat towards the left in this "PLAN" image and we are viewing the ecliptic plane from top (from ecliptic north pole) - hence, in the "FRONT ELEVATION" and "SIDE" views, we would see the ecliptic plane as a thickness (with ecliptic north pole towards the top and ecliptic south pole towards the bottom in this image) - hence, submitting the above points for review.

CURRENT STATUS : the original graphic contributor is looking into this matter.
