They're more likely to just be knocked out of orbit altogether and wind up adrift in outer space. But with the vast distances between stars, even that's very unlikely.
hold on a minute if the stars do high speed laps would that mean that a star slightly closer to the center of our galaxy(about the orbit of venus) wouldnt it get into our solar system?(and if alot smaller start to orbit like in the solar system andromeda)?
Stars closer to the center of the galaxy do move "faster" (when measured in the amount of time it takes them to make a revolution), so just like in the Solar System, they'll appear to be in different places in the night sky over millions of years. But there's so much space between stars, that none of them will ever actually come into our Solar System, just change position relative to it.
no way!!! its a rong theaory... if stars move then planets move with them also?? how about comets,,, lol there is something wrong with this theory.. doesnt sound right..
Yep, the planets and things that are in orbit with the stars go right along with them. The same way you go right along with the Earth as it orbits the Sun.
Yep, comets, too. They just have more eccentric orbits around their stars, and are easier to disturb if two stars pass too closely to one another. There are some theorists that think that the dinosaurs were killed off because our sun passed close to another star, disturbing the comet in the Oort cloud, which then got shifted closer to Earth and eventually smashed into the planet, causing a mass extinction. The jury's still out on that one, though.
you guys are awesome. i run a computer lab for 3rd through 5th graders. we use celestia and stellarium in the lab and the kids love them both. i'm going to start showing your lineup of videos. great work!
Ancient astronomers didn't have telescopes. The five visible planets looked just like stars to them. But the rest of the stars looked like they stayed in the same place relative to each other, and the five planets (which means "wanderer") were in a different place relative to the other stars every night.
We've actually got a video about that coming up very soon.

I love the animations 8D

hmmm what if we go near another star can the planets get exchanged between orbits?

lol... ok.. planets make sense cuz they follow sun... hmmm but how about comets.. dont tell me comets follow sun's gravity!!? wat about that
