Isn't the sun revolving around the center of the milky way at approximately 450,000 mph? And the Earth revolves around the sun, so we're moving about half as fast as this new object right now. One million is pretty fast, but context makes it a little less shocking.
That's not context, that's using arbitrary reference frames.
What's the difference?
It's like claiming you can beat Usain Bolt by sprinting in a moving train. Sure, with respect to ground you cover the distance faster than him, but it doesn't make much sense to count it that way.
That's not an analogy at all, as it's completely different from what i said earlier. I'm not trying to prove that Earth is moving amazingly fast, I'm trying to show how the headline seems grander than it is.
I also don't think a lot of people realize quite how fast the Earth is moving through space. Saying a million miles an hour really does seem impressive if you don't have that information. But as we speak, we are literally hurtling through space at half that pace.
If we weren't orbiting the sun we would end up orbiting something else at a different speed.
This would be similar to saying that San Bernardino county in California is 20000 sq mi, or about 50k km squared. It's just a number without context. But if i told you it's a county that is it was bigger than both the country of Switzerland and US State of West Virginia, that's added context for size comparison. The way that California divides its county structure does not invalidate this comparison, and is irrelevant.
I'm not really sure what your intent or point is here.
I don't think that's entirely fair to say. The headline reads sensationally about a celestial object, but our own sun is traveling at almost half that speed, and we're following it. I'm not trying to prove that the Earth is incredibly fast, only that the headline may sound more impressive than it is.
