Article is totally wrong about parallax. It’s relative apparently motion, nothing to do with brightness.

- btilly 8y agoI have no idea why anyone would vote this correct statement down. See https://en.wikipedia.org/wiki/Stellar_parallax https://en.wikipedia.org/wiki/Stellar_parallax for verification.
- skybrian 8y agoParallax does come in separately, in the part about the relative size of the earth's orbit compared to the distance to the stars.
- joshumax 8y agoI had something of a double-take on this part too. A difference in apparent magnitude throughout the year isn't the same as stellar parallax by any means, and is something of a misnomer.
