Are there any stars that float free from their galaxies. Any planets that are free from their stars?

Question

The image we have is of stars existing in great galaxies, but there being vast tracts of empty space between the galaxies.
But I wonder whether any stars have ever broken free of their galaxies and are wondering freely through space billions of light years away.

Equally could a planet have broken free of a star, and float throught space frozen solid light years from the nearest star.

Answer 1

All the stars we can see are in our own galaxy. We can see the blurs of other galaxies but can not really make out individual stars in them. We can't see any stars in between the galaxies, but they could be there and not be seen because they are so far away. Similarly, rogue planets could exist, but we wouldn't be able to see them if they are not illuminated by a star.

Answer 2

Our galaxy is made out of billions of stars extra or a lot less like our solar. some are brighter, some are fainter. some are larger, some are smaller. almost each and every thing you spot contained in the sky at evening is a movie star reminiscent of our solar, placed close by in our area of the Milky way. the in user-friendly words exceptions are the planets, that are closer to us and shine by technique of pondered photo voltaic, and some exterior galaxies, so distant that we received't settle on stars in them. they appear to be detached products of the Milky way: faint fuzzy glows, not in any respect like stars.

Answer 3

probably not The escape velocities are pretty high so a lot of additional energy would need to be added. That nmeans some catastrophic event such s a collision of some sort

Answer 4

Hi. Definitely yes to both questions. The only stars which seem to be bound together more or less permanently by gravity are in globular clusters.

Answer 5

They have already found unattached stars and planets.
