Coordinates
[edit]This cites what appear to be precise-coordinate conversions of imprecise coordinates that would indicate a rather rough determination. If so, good science demands that this be made clear. 74.69.160.254 (talk) 17:24, 26 June 2023 (UTC)
There does not seem to be any reliable reference for "solar apex". The only paper that mentions the term is the 1980 Hoskin, Michael paper.
The article should have a source for the definition (Hoskin would work) and the direction. As it is we have some editors making claims by combining data from sources: that is synthesis right? Johnjbarton (talk) 20:43, 26 May 2024 (UTC)
Location
[edit]According to your star map, the little dot is in Lyra, and much closer to the main part of Lyra than to the main part of Hercules. The maps are much easier to read with "invert color", that is: white sky with black stars. That is the most common way that star maps are published. You should also provide that type so that viewers do not have to do their own conversions. Viewers that need to print the maps need to have the white sky versions. If you feel that only one type should be here, then get rid of the black sky/white star versions. agb 173.233.167.51 (talk) 18:59, 6 December 2024 (UTC)
History
[edit]There must be an interesting history of the concept. What observations lead Herschel to conclude that there was a phenomenon? I don't think that there was capability to observe spectral shifts as indicating motion. And wasn't it assumed that the Sun was motionless, so that the stars were streaming past the Sun? And then it was some evolution of the understanding of the structure of the Milky Way, and the Solar Systems' place and motion in it. 06:59, 18 March 2025 (UTC) TomS TDotO (talk) 06:59, 18 March 2025 (UTC)
- According to the Hoskin ref cited in the article:
Throughout the eighteenth century astronomers and cosmological speculators considered the possibility that the Sun and the solar system are moving through space
- I added some content about Herschel's work. He had tables of star motions to work from. I believe the basic assumption was "fixed stars" so changed would be attributed to solar motion. Johnjbarton (talk) 02:39, 19 March 2025 (UTC)
