How thick is the Milky Way in miles?

Size and mass The Milky Way is the second-largest galaxy in the Local Group (after the Andromeda Galaxy), with its stellar disk approximately 170,000–200,000 light-years (52–61 kpc) in diameter and, on average, approximately 1,000 ly (0.3 kpc) thick.

How big is the diameter of the Milky Way?

Milky Way/Diameter

What is the diameter of the Milky Way galaxy in which we live?

100,000 light-years
NASA estimates the galaxy at 100,000 light-years across. Since one light year is about 9.5 x 1012km, so the diameter of the Milky Way galaxy is about 9.5 x 1017 km in diameter.

How do we know where we are in the Milky Way?

“There is no short answer to this question, because astronomers have followed many lines of evidence to determine the location of the solar system in the Milky Way. “The position of the sun in the Milky Way can be further pinned down by measuring the distance to all the stars we can see.

How big is Milky Way?

The Milky Way is a barred spiral galaxy with a diameter between 150,000 and 200,000 light-years (ly). It is estimated to contain 100–400 billion stars and more than 100 billion planets.

Where is the Milky Way located in the universe?

The Milky Way (天の川, Amanogawa) is a galaxy in the 7th Universe, and is one of the North Galaxies overseen by the North Kaiō. Located at the very edge of the 7th Universe, the Milky Way is central to the Dragon Ball series, as it is where a majority of the series occurs.

How many miles is the Milky Way from Earth?

The Milky Way’s center is 26,000 light-years from Earth, and Sgr A* is measured to be about 14 million miles across.

How long to orbit Milky Way’s center?

Our Milky Way galaxy is a big place. Even at this blazing speed, it takes the sun approximately 225-250 million years to complete one journey around the galaxy’s center. This amount of time – the time it takes us to orbit the center of the galaxy – is sometimes called a cosmic year. See a range of estimates for the length of a cosmic year here.
