Results for “how many stars in our solar system” · retrieved September 22, 2026
There is only one star in our solar system, which is the Sun.
Our solar system is a single-star system, meaning it contains only one star, which is the Sun. The Sun is located at the center of the system and contains the vast majority of its mass, with all other objects—including planets, dwarf planets, moons, asteroids, and comets—orbiting it. While the Milky Way galaxy contains hundreds of billions of stars, our solar system is defined by the Sun and the objects gravitationally bound to it.
Answer details
Single-star system
The Sun is the only star in the solar system and serves as its central, dominant gravitational body.
Mass dominance
The Sun accounts for approximately 99.8% to 99.86% of the total mass of the entire solar system.
System composition
The solar system consists of the Sun and all objects bound to it by gravity, including eight planets, dwarf planets, moons, and millions of smaller bodies.
Galactic context
While our solar system has only one star, it is located within the Milky Way galaxy, which contains hundreds of billions of other stars.

Solar System: Facts
Our solar system includes the Sun, eight planets, five officially named dwarf planets, hundreds of moons, and thousands of asteroids and comets. Our solar system is located in the Milky Way, a barred spiral galaxy with two major arms, and two minor arms. Our Sun is in a small, partial arm of the Milky Way called the Orion Arm, or Orion Spur, between the Sagittarius and Perseus arms. Our solar system orbits the center of the galaxy at about 515,00

Chapter 1: The Solar System - NASA Science
Our whole solar system, along with all the local stars you can see on a clear dark night, reside in one of our galaxy's spiral arms, known as the Orion arm, as they orbit the supermassive black hole in the dense star cluster at the center of our galaxy some 26,000 (±1400) light-years distant from us. At this great distance, we go around once about every 250 million years. Stars very close to the central mass are observed in keplerian orbits with
