You can detect planets around are star only if they are of sufficient mass, They will cause the star to wobble (due to its gravity) as it rotates this can be seen and the position of the planet inferred.

What is a central star with planets around it?
solar system
Are there more Stars or Planets?
there are more planets than stars because to every star there could have several planets
What do scientists look for when they are trying to find planets around other stars?
The first discoveries of extra-solar planets were made by looking for a slight wobble in the motion of the star. In the last couple of years, scientists have been able to detect the change in the spectrum of a star as a planet passes in front of it, and be able to analyze the atmosphere of that planet.
Is our sun the only star that has planets orbiting around it?
No. Other stars have been found to have planets orbiting them.
Large bodies of rock or gas that revolve around a star are called?
Large bodies of rock or gas that revolve around a star are planets.
How does the Kepler mission plan to detect Earthlike planets around other stars?
by observing the slight dip in brightness of the central star as the planet transits
Why can't hubble be used to detect extrasolar planets?
It actually can and is used to detect extrasolar planets, mostly through watching their transits, where they move in front of the star and block some of its light.
What is a core of rock and ice attracts gases?
A core of rock and ice that attracts gases is likely referring to a comet. Comets are celestial objects composed of rock, dust, ice, and frozen gases that orbit the Sun. When a comet's orbit brings it close to the Sun, the heat causes the ice to vaporize, releasing gases and creating a glowing coma and tail.
What planets go round the stars?
All 8 planets in our solar system rotate around a star, our sun. Virtually all planets rotate around a star.
How do astronomers observe planets that are too far away to see?
Space Telescopes Planets that are orbiting stars that are far away creating fluctuations in the light that we see coming from the star. Astronomers can observe those planets by measuring the fluctuations of that light.
What are large bodies of rock or gas that revolve around a star called?
Large bodies of rock or gas that revolve around a star are planets.
Do the planets revolve around the earth?
No all planets revolve around the nearest star. In our case, the sun.
Are there planets around black Star?
It is quite possible that a black hole could have planets orbiting it. Some pulsars (neutron stars) have confirmed planets, something that was thought impossible. The problem is however, we would be unlikely ever to be able to detect them. Most current methods such as the dopler method, gravitation micro-lensing and the transit method rely on the central star emitting electromagnetic radiation (light etc). Black Holes by definition do not shine. The only way i can conceive you could detect planets around a black hole is to detect and observe a black hole with an accretion disk and look for disturbances within the disk. I could not say if it is possible for such a planet to retain a stable orbit.
Are all suns stars?
No, all stars aren't suns. A sun is a star that is at the center of a solar system. Planets rotate around the sun. Planets don't rotate around a normal star. A star can be found anywhere around the universe. That's not the case with planets. Planets have to be in a solar system and a sun has to be in the center. If this is the case with a star, then that star can be called a sun.
Why do you suppose all the other sun like systems we know about have only 1 huge planet within 2 AU of its star?
We currently have the ability only to detect large planets that are close to their parent star, but as the technology progresses, we will be able to detect smaller planets, and planets that are further away. Also, astronomers have found systems of planets, meaning stars that have more than 1 planet.
Is there a sun for every solar system?
Yes, that's the idea of a "solar system". A star (sun) in the center, and planets going around it.Yes, that's the idea of a "solar system".

Do the star planets orbit around the sun?
I'm not sure what you mean by "Star planets." However, I can tell you that there are 8 known planets that orbit the star Sol, including Earth (Sol 3).
