![]() “In the helical model, he shows the planets as orbiting around the Sun perpendicular to the motion of the Sun around the galaxy “face-on”, if you like.This is wrong. What the gif definitely does not show is the fact that the orbits of the planets are tilted at about 60 degrees to the direction of the Sun’s motion. For now, just keep in mind that Sadhu is using an alternative model, even though that may not always be evident. Actually I couldn’t find a whole lot that was even vaguely coherent, but we’ll return to this later. I’ve glanced at it, but couldn’t find anything stating this precisely. On the other hand, Plait read the source material for Sadhu’s model, so maybe there’s something in there that’s more explicit. that things can look different from different angles. It seems to me that the appearance of the Sun leading the planets in the gif is just the result of a projection effect – i.e. In fact, some of other videos on his website clearly show that this isn’t the case: Having read through the author’s website, I can’t find any evidence that he suggests this. Yet I’m not so sure the viral gif does show the Sun leading the planets. But first, if the Sun was really leading the planets, then the thing is completely ludicrous (and this is quite a major part of Plait’s argument). Like this: Credit : Science Minus Details The orbits of the major planets of the solar system all lie in a narrow plane (like being in economy class! hahaha… sorry), which is tilted at about 60 degrees to the disc of stars that forms the Milky Way. “ Sometimes the planets really are ahead of the Sun as we orbit in the Milky Way, and sometimes trail behind it (depending on where they are in their orbit around the Sun).” “Sadhu shows the Sun leading the planets, ahead of them as it goes around the galaxy… This is not just misleading, it’s completely wrong.” But then I read Phil Plait’s analysis, and it seems that things are much, much worse than that. Obviously the orbits and size of the planets are not to scale (and I think their orbital speeds have be altered too), but that’s just to make them visible. Like many people, I was at first glance really quite impressed with the video, and didn’t have any major objections to it.
