No, although it is difficult to spot exoplanets, so only the larger ones are often found. Most systems with identified planets most likely have many other smaller planets that we cant detect. A planet the size of Earth or Mercury is nearly impossible to detect with current technology.

How scientist know stars have planets?
Planets can cause the star to have a very slight wobble or shift in normal path. This is picked up by a spectrogram. Some planetary systems actually have dust clouds around the star.
How many planets in your univerese?
The number of planets is not known. The number of stars is not known either, nor if all have planetary systems. Certainly many billions of billions.
What is the sun and all the planets around it called?
It is called the solar system. There are also systems around other stars.
How do you think the formation of the new stars is related to supernovas and planetary nebulae?
i don't konw?
Which is larger soalr system or globular cluster?

Are there other planetary systems around other stars?
Yes. Many stars have planetary systems.
What are groups of solar systems called?
The Solar System is the name of our particular planetary system around our star; Sol. Many stars have been observed to have similar planetary systems and it can be assumed this is a common event in the Universe. Often neighbouring stars will form small groups called clusters, but the Universe is populated by huge groups of stars called galaxies which contain anything from a few million to trillions of stars.
How many stars make up the constellation Aquarius?
Aquarius is made up of 16 stars. The constellation contains no particularly bright stars. It does, however, have planetary systems in the stars within its borders.

Is a galaxy part of your solar system?
No, it's the other way around; our solar system is a (very tiny!) part of our Galaxy. Our galaxy is many BILLIONS of stars, most of which probably have (or perhaps, once had) some sort of planetary or asteroid system in orbit around them. Scientists once thought that planetary systems like our solar system would be scarce. But recent discoveries have found planets circling many or most of the nearby stars.
What are stars systems?
its two stars that share the same orbit around each other
How many planets in your univerese?
The number of planets is not known. The number of stars is not known either, nor if all have planetary systems. Certainly many billions of billions.
Which one is the biggest the planetary system or galaxy?
A galaxy is far larger. A planetary system involves one or more planets revolving around a single star. A Galaxy consists of billions of stars.
How are planetary nebulas different from stars?
Stars are balls of gas that undergo nuclear fusion and have a core, their light come from the energy released during nuclear fusion. Planetary nebulae are the blown-off shells of dying red giant stars, the light of a planetary nebula come from ionized gas and light of other stars.
What planetary bodies create their own light?
Stars.
How do you use planetary nebula in a sentence?
A planetary nebula consists of gas ejected from old red giant stars.
Is planetary nebula a misnomer?
Planetary nebula is a misnomer because it's a nebula but it has nothing to do with planets, it's about stars.
