There are billions of planets in the galaxy. Most of them have no names and have not been observed yet.
As of 1 September 2017, there have been confirmed detections of 3,660 exoplanets in 2,744 planetary systems and 614 multiple planetary systems.
Galaxies are generally a collection of stars. But within any galaxy, there are lots of other objects, including planets. So galaxies are related to planets in some ways.
None. Galaxies on the other hand do contain planets
It is possible that every galaxy has some planets. We just are starting to detect some planets in other galaxies.
yes we can live
Very probably
Well, we don't know whats all out there because it's hard to get into other galaxies, but we think its the only one with planets. (We don't know for sure so do some more research)
There are many other planets in many other galaxies.
Probably, though most planets discovered so far - or perhaps all of them - are in our own galaxy. The reason for this is simply that it is easier to discover planets when they are relatively close to us. But, having discovered about a thousand planets nearby, there is no particular reason to believe that other galaxies would be devoid of galaxies. After all, the same laws of physics work in other galaxies as here.
To know what is the life there, and if there's any other creatures or "aliens". some scientists are looking for planets with water and life on them.
Asteroids, some comets, and dwarf planets are classified as minor planets. Stars and galaxies are much larger than planets There are dwarf planets and these are Ceres Pluto and Eris.
They take some tacos and throw them in space and see if they hit another planet.
We don't have the means to detect or observe planets in other galaxies. But so many hundreds of them have been discovered in our own galaxy that it's a safe bet that other galaxies must have them too, in abundance.
