The galaxy is moving through space at 343 to 391 km/sec, but compared to what? What is the frame of reference? And is our star moving at the same speed as all the other stars around it, and the planets and moons and dust motes, or is our star moving faster or slower, and do the dust motes stay where they are?
I’ve seen this first question before and don’t recall the answer and can’t think of a quick place to look, other than go to Google. Nor do I know the answer to the other questions. Would love to know them and hope it’s possible to have this kind of conversation around this website. You’re the first commenter, so I’m also in the dark about how the comments get into the public realm, other than to appear on the page. And thanks for reading and commenting.
