That is very likely, although for obvious reasons, all planets discovered so far (or most of them?) are in our own galaxy.
Through intense research it has indicated that stars are not only luminous balls of plasma held by gravity, but are also planets from different galaxies. From a distance, they may seem like stars, but are in fact planets. So yes, you are correct, planets are stars from different galaxies.
None. Galaxies on the other hand do contain planets
Probably, but impossible to tell as we are only just seeing planets within our own galaxy.
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.
Constellations are stars put together, usually to form a ancient figure in the stars, a galaxy is much different, They have planets and in galaxies you can find constellations. Big difference
The Universe Is the whole, where all the galaxies are, and galaxies are just big clusters of starts, planets and different types of debris.
yes we can live
More planets. A typical galaxy probably has billions of planets.
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.
Astronomy.
Very probably
About 60% of galaxies are classified as elliptical planets.
