All I can think of is aliens. I can’t think of anything in nature that could get a planet moving that fast.
Now a much more dense object like a mini black hole? That’s a more interesting question.
Comment on what would happen if a rogue, earth-size planet ran straight into the sun? anything interesting?
teft@lemmy.world 3 months agoNow I’m imagining the type of event that could cause a planet to move at such a significant percent of c that you could disrupt the sun with it. I don’t think we’re gonna get a planet moving that fast. I think we’d be limited to stellar core remnants to get that kick in velocity.

Could it go fast enough that it doesn’t have enough time to absorb significant amounts of heat and pops out the other side basically intact?

We are going to collide with the Andromeda galaxy maybe 1 billion years before the sun fizzles out. Something there with opposite galactic orbit from us could smack into our sun at over 700 km/s.

As it is, our entire solar system is orbiting at 514,000mph or about 1/1300th the speed of light relative to the center of the galaxy. And the Milky Way Galaxy is moving at about 1.3 million mph through the universe.
