Firstly, planets are way way smaller than the stars! That's because you can see stars in the night but never planets. Also stars produce nuclear energy in their core so they give thermal ( heat ) energy. Also stars have more gravity than planets.
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.
No. We know what the stars are. They are not planets. They are distant suns, many of which do have undiscovered planets.
A planets and stars are different things, so a planet can never be a death star.
Plants are normal and stars are like comets
Planets orbit stars, stars orbit a galaxy. Planets are not "on" anything. A lot of stars out there have planets - we are just finding out how many now that we have better techniques to find them. So probably all galaxies have at least some stars with planets.
hundreds of stars and planets
Milky way is talking about our whole actual galaxy with a lot of stars, planets, asteroids, meteors, and comets, but solar system JUST refers to our sun, the moon, planets, and the stars which happen to be in the Milky way. They are two totally different things because of this.
All of the planets are in the same atmosphere. All of the planets are unique. All of the planets are considered planets. All of the planets have moons. All of the planets are named after a mythical person or thing.
because they're way closer than the stars
Planets orbit stars, moons orbit planets. That is the only difference.
Planets orbit stars.
