Milky Way 3D map: where is Earth in the galaxy?

Earth and the Sun are about 26,700 light-years from the centre of the Milky Way, in the Orion Arm, around 67 light-years above the galactic plane.

GalaxySim 3D places 36 nearby and bright stars, 16 nebulae, clusters and galaxies, and the galactic centre at their real positions — fly out from Earth and watch the solar system shrink to a point.

Frequently asked questions

Where is Earth in the Milky Way?

About 26,700 light-years from the galactic centre, in the Orion Arm (also called the Orion Spur), a minor spiral arm between the larger Perseus and Sagittarius arms. The Sun is roughly 67 light-years above the galaxy’s mid-plane.

How big is the Milky Way?

Its disc of stars is roughly 100,000 light-years across and only about 1,000 light-years thick, holding an estimated 100 to 400 billion stars.

What is the closest star to the Sun?

Proxima Centauri, 4.25 light-years away. Light from it takes over four years to reach us; Voyager 1 would need more than 70,000 years to get there.

What is at the centre of the Milky Way?

A supermassive black hole, Sagittarius A*, about 4 million times the mass of the Sun. Its shadow was first imaged by the Event Horizon Telescope in 2022.

Can I see the Milky Way in 3D?

Yes. In GalaxySim 3D, zoom out from the Sun past the nearby stars and the galaxy appears around you, with the galactic centre, the Magellanic Clouds and Andromeda at their real directions and distances.
