What an excellent question. It appears you already realize that if you are talking about stars other than our sun, you are talking about stars that are many lightyears away from us, and not even powerful telescopes will easily detect planets orbiting around them. One thing that astronomers can sometimes detect is the slight wobble of distant stars as planets orbit around them. You might not realize that suns would move as a result of a planet's orbit. Imagine you and a friend holding on to the ends of a rope. If you begin to move in a circle, you will each feel the centripedal force pushing you outward. Neither of you would be able to stand perfectly still while the other circled with the rope. Another thing that astronomers can detect using very sensitive equipment is the slight reduction in brightness of a star when a planet's orbit brings the planet between us and its star. If this reduction in brightness is regular enough, it may be an indication that there is a planet in orbit.

Do stars orbit planets or planets orbit stars?
Planets orbit stars.
What is hotter planets or stars?
stars, the planets have to get heat from stars
Which galaxy are the planets on?
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.
How do you know where a black hole is?
You will see stars/planets orbiting what looks like nothing.
Do the stars or dwarf planets orbit planets?
No. Dwarf planets orbit stars just like planets do. Stars orbit the center of their galaxy. An object orbiting a planet would be a moon.
Where are the planets found?
Orbiting stars. We know of eight planets orbiting our Sun, and we know of over 300 planets orbiting other stars.
Are the stars in the sky different planets and moons we have not discovered yet?
No. We know what the stars are. They are not planets. They are distant suns, many of which do have undiscovered planets.
Do stars orbit planets or planets orbit stars?
Planets orbit stars.
How do you know the location of the future by the movements of the planets and stars?

How much planets do we now?
We know of eight (8) in our solar system, and we know of a few hundred other stars that have planets although we can't actually see the planets.
How do scientists know that planets are closer to earth than the stars?
not a clue
Why do planets need their stars?
Planets do not technically need their respective stars, but stars keep planets in orbit and provide heat and light to the planets.
Are thyere other planets close to a black hole if so what are they?
I don't think there would be planets, but I know there are stars!
Do planets and moons have stars?
On the contrary! A star has planets, which circulate it. And planets have moons. Stars do not circle planets.
Which pulling force do planets and stars have?
Planets and stars have gravity.
What makes stars and planets?
The Solar System Makes the planets and the Stars.
