Nearest solar system in our galaxy

Which star is closest to Earth?

The closest system is Alpha Centauri, with Proxima Centauri as the closest star in that system, at 4.2465 light-years from Earth. The brightest, most massive and most luminous object among those 131 is Sirius A, which is also the brightest star in Earth's night sky; its white dwarf companion Sirius B is the hottest object among them.

Which star is closest to Alpha Centauri?

Alpha Centauri consists of three known stars (including Proxima). Of the three, Proxima is closest, at 4.2 light-years away. Alpha Centauri appears as the 3rd-brightest star in Earth’s sky. But Proxima is too faint to see with the eye. It’s a small, dim, low-mass star, with its own planetary system.

Are all stars in the Milky Way galaxy?

Our Sun (a star) and all the planets around it are part of a galaxy known as the Milky Way Galaxy. A galaxy is a large group of stars, gas, and dust bound together by gravity. They come in a variety of shapes and sizes. The Milky Way is a large barred spiral galaxy. All the stars we see in the night sky are in our own Milky Way Galaxy.

Is there a second planet around the star Proxima c?

In June 2020, scientists announced that they had discovered a second planet around the star, Proxima c. This second planet for Proxima is a lot larger than Earth and orbits its star every 1,907 days. It orbits at about 1.5 times the distance from its star than Earth orbits from the sun.

How far away is our Solar System from the center?

Our Solar System is about 25,000 light years away from the center of our galaxy – we live in the suburbs of our galaxy. Just as the Earth goes around the Sun, the Sun goes around the center of the Milky Way. It takes 250 million years for our Sun and the solar system to go all the way around the center of the Milky Way.

Where is the Solar System located?

The Solar System, and the other stars/dwarfs listed here, are currently moving within (or near) the Local Interstellar Cloud, roughly 30 light-years (9.2 pc) across. The Local Interstellar Cloud is, in turn, contained inside the Local Bubble, a cavity in the interstellar medium about 300 light-years (92.0 pc) across.
