How scientist know stars have planets?
Scientists know that stars have planets through various methods, including measuring the wobble of a star caused by a planet's gravitational pull, observing the dimming of a star's light as a planet passes in front of it (transit method), and direct imaging using powerful telescopes. These methods have helped identify thousands of exoplanets orbiting distant stars.
Are there moons and stars on planet earth?
No, there are not moons or stars ON planet earth, but there are moons and stars around planet earth. == ==
What effect do planets have on the stars they orbit?
The gravity of the star is usually many times larger than the planets due to the overwhelming mass of the star in comparison. The planets do have a gravitational pull of their own though, which has an effect on the star it is orbiting. It will cause the star to move slightly off centre as it pulls on the star during its orbit. The bigger the planet, the bigger the pull. By looking at distance stars, astronomers can see the effects of planets by observing a 'wobble' in the star as the unseen planets orbits it. They can then calculate the size of the planet and distance by the size and speed of the wobble.
What planet contains trillions of stars in the solar system?
No planet contains any stars because stars are always much larger.
What can the distances to nearby stars be measured by?
Light years
How did scientist find planets orbiting stars than your sun?
they study the stars, watch them for long periods to discover if they wobble. if they do then they have a gravitational pull on a planet
Why cannot you see planets around stars through telescopes?
We can, except we see them by the wobble of the star. The planet itself is too faint for our telescopes to see, but the gravitational pull the planet places on the star causes it to wobble and we can observe that through time-lapse observations.
Why do stars wobble?
Stars wobble due to the gravitational influence of the planets orbiting them. As planets orbit their stars, their gravitational pull causes the stars to move slightly in response. Scientists can detect this wobble in a star's position, which provides information about the planets orbiting it.
What planet is a nearby galaxy?
A galaxy is a cluster of stars and gasses and a planet is something that goes around a star. Can you see why this might not make sense?
How are star systems identified?
Depends on what you mean by star systems. If you mean solar systems, we use two main ways to determine if there are planets. We use the "wobble" method, in which the planet causes the star to wobble. We can tell the orbital speed and size of the planet by the frequency of the wobble. We also use the light of the star itself. If a large enough planet passes in front of the star, it will dim slightly. We can also tell the approximate size and orbital period of the plane by how often, and to what extent the star dims. Star systems can consist of one or more stars (the Alpha Centauri system has three stars orbiting each other).

How many stars are there in a dwarf planet?
None. No planet or dwarf planet contains stars.

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.
How are planets detected around other stars?
Planets around other stars are typically detected through indirect methods, such as the transit method (observing a star's brightness dip as a planet passes in front of it) or the radial velocity method (observing the star's wobble caused by the planet's gravitational pull). Other techniques include gravitational microlensing and direct imaging using specialized telescopes.
How many stars are in the planet?
Planets have no stars in them.
