Is there evidence that there are other planets orbiting other stars?

Yes, there is. There is evidence of over 300 "exo-planets", planets that are orbiting other stars.
Because the pull of gravity goes both ways, it can be said that a sun orbits the planet in addition to the planet orbiting the sun. Because suns are much more massive than planets, the motion of the planet in its orbit is far greater than the motion of the star, but the stars DO "wiggle" a bit. This "wiggle" is sometimes detectable, especially if the planet is itself quite massive - like a "super-Jupiter".
And sometimes, the planet passing in front of the star blocks a teeny bit of the starlight, causing the star to appear to be slightly less bright.

Is our sun the only star that has planets orbiting around it?
No. Other stars have been found to have planets orbiting them.
Are there other planets Andromeda galaxy?
We expect the Andromeda galaxy to be just like our own Milky Way galaxy. We can see stars (suns) in the Andromeda Galaxy and just as stars have planets orbiting them in our galaxy, we believe that there must be planets also orbiting stars in the Andromeda galaxy.
Do any of the stars you can see have planets around them?
Yes. To date scientists have discovered well over a thousand planets orbiting other stars. It is believe that a large portion of the stars in the night sky have planets.
Is it true that Kepler's laws holds only for the six planets known in his time?
No. It holds for other planets, and for any other situation where one objects orbits another - for example, moons orbiting planets, stars orbiting a black hole, etc.
What do astronomers think about the possibility of planets orbiting other stars and being detected?
Hundreds of extra-Solar planets have been detected already.
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.
Is our sun the only star that has planets orbiting around it?
No. Other stars have been found to have planets orbiting them.
Where are ExtraSolar planets found?
Extrasolar planets are planets found orbiting stars other then our own.
What is a group of stars and the planets and other objects orbiting around it?
Solar system
Are there ant planets orbiting gemni?
There may be planets orbiting stars in the constellation Gemini, but planets do not orbit whole constellations.
Are there Earth like planets?
Perhaps orbiting around other stars, but we have yet to find them.
Are there other planets Andromeda galaxy?
We expect the Andromeda galaxy to be just like our own Milky Way galaxy. We can see stars (suns) in the Andromeda Galaxy and just as stars have planets orbiting them in our galaxy, we believe that there must be planets also orbiting stars in the Andromeda galaxy.
Are planets outside the solar system?
A solar system comprises a star (or combination of gravity bound stars) and their orbiting planets. We think the majority of stars are solar systems an we have detected planets orbiting stars other than the Sun. However in the process of forming a solar system we believe that planets my be permanently ejected from orbiting their stars and flung off into interstellar space. These planets would therefore indeed be outside any solar system.
Does circular motion occurs only occures only on earth?
No, there are circular movements just about anywhere: planets, moons and stars rotating, planets orbiting their stars, moons orbiting their planets, and stars orbiting their galaxies, often in orbits that are fairly circular, etc.
Do any of the stars you can see have planets around them?
Yes. To date scientists have discovered well over a thousand planets orbiting other stars. It is believe that a large portion of the stars in the night sky have planets.
What other planets are in the milky way galaxy?
All the planets we know of... even those orbiting other stars... are in the Milky Way Galaxy.
Are there any planets out of our solar system that orbit around stars?
Yes. As of August 2015 scientists have discovered nearly 2,000 planets orbiting other stars.
