what is our star system？
Our solar system consists of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such as Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids.2021年8月30日
Subsequently,Is our star system binary?
A team of Harvard astronomers have a wild new theory: the Sun used to have a companion star, making our solar system a binary one during its ancient history.Harvard Astronomers Propose That Our Star System Used to Be Binaryhttps://futurism.com › harvard-astronomers-star-system-bi...https://futurism.com › harvard-astronomers-star-system-bi...
Correspondingly,What is our solar system star?
The Sun is the only star in our solar system. It is the center of our solar system, and its gravity holds the solar system together. Everything in our solar system revolves around it – the planets, asteroids, comets, and tiny bits of space debris.Overview | Sun – NASA Solar System Explorationhttps://solarsystem.nasa.gov › solar-system › sun › overviewhttps://solarsystem.nasa.gov › solar-system › sun › overview

What was here before Earth?
So let's go back, more than 4.6 billion years, before there was an Earth, a sun, or even a solar system.

What was before sun?
Approximately 4.6 billion years ago, the solar system was a cloud of dust and gas known as a solar nebula. Gravity collapsed the material in on itself as it began to spin, forming the sun in the center of the nebula. With the rise of the sun, the remaining material began to clump together.How did the solar system form? - Space.comhttps://www.space.com › 35526-solar-system-formationhttps://www.space.com › 35526-solar-system-formation

Namely, every Sun is a star, but not every star is a Sun. The Sun is larger and as such a lot brighter than most stars. There are billions of Suns in our galaxy alone and as mentioned, many of the stars we see are also Suns.
