There is only one, the Sun. All other stars are outside the solar system. The Sun is a very ordinary star that just happens to be very close. Many of the stars we see in the sky are bigger and brighter than the Sun, only a lot further away.

Planets moving around stars have been directly observed outside the solar system?
False. No planet has been directly observed. All planets (exoplanets) have been detected using non direct methods or inferred methods.
How many stars in the milky way galaxy have earth like planets?
This is not known yet. Hundreds of planets have already been found outside our Solar System, but earthlike planets can, for the most part, not be observed with current technology.
On what percentage of the Moon's have eruptions been observed?
About 50% of the moons in our solar system have eruptions. Only about 2% to 5% are actually observed, but there is sufficient evidence that others have occurred.
What is a group of planets and their moons that orbit a central star?
A group of planets moving around a star is called a solar system. Planets outside our solar system are called exoplanets. Despite the difficulty of detection, many hundreds have been discovered recently, orbiting other stars.
Is a solar system made up of stars and objects that surround it?
Our solar system is made up of one star - the Sun - and everything held in orbit around it. Some distant stars have been determined to have planetary objects surrounding them, too, but there is still more unknown about those than known.
How many stars have been observed in your solar system?
So far, we've only noticed one- We revolve around it and call it 'the Sun'.
Planets moving around stars have been directly observed outside the solar system?
False. No planet has been directly observed. All planets (exoplanets) have been detected using non direct methods or inferred methods.
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 long have stars been around for?
Ever since the world and the solar system were created.

How many planet is struenis a way from the sun?
There is no object in our Solar System that has been discovered, observed, and given the name 'Struenis'.
Is our solar system also our galaxy or is there more than one solar system in the milky way?
No, our Solar System is not the galaxy. Our Solar System is the Sun, and the planets around it (plus a few other objects, such as asteroids and comets). Our Sun (the center of our Solar System) is a star; in the galaxy there are several hundred billion stars, each of which might be called a solar system. At least if it is confirmed that it has planets - but it has already been confirmed that many stars in our neighborhood have planets.
Where Astronomers expect to find planetary system?
Anywhere there are stars. Hundreds of planets have already been discovered outside our own Solar System.
Is the solar system the only system in out galaxy?
No, it's thought that most of the 200 billion or so stars in our galaxy are solar systems themselves, with planets in orbit around them. These are know as exosolar planets, many have been identified through their gravitational effects on the stars.
What is a group of planets and their moons that orbit a central star?
A group of planets moving around a star is called a solar system. Planets outside our solar system are called exoplanets. Despite the difficulty of detection, many hundreds have been discovered recently, orbiting other stars.
Is there other solar systems around the stars?
Yes, hundreds of "extrasolar" planets, i.e., planets outside our own Solar System, have already been discovered.Yes, hundreds of "extrasolar" planets, i.e., planets outside our own Solar System, have already been discovered.Yes, hundreds of "extrasolar" planets, i.e., planets outside our own Solar System, have already been discovered.Yes, hundreds of "extrasolar" planets, i.e., planets outside our own Solar System, have already been discovered.
