How many miles to the edge of the Milky Way?

about 950,000 light-years
This occurred at a distance of about 950,000 light-years from the Milky Way’s center, marking the galaxy’s edge, the scientists say. The edge is 35 times farther from the galactic center than the sun is.

How long would it take for light to travel from one edge of the Milky Way galaxy to the other?

A new study shows it would take 200,000 years for a spaceship traveling at the speed of light to go across the entire galaxy.

How far away is the edge of the observable universe?

46.5 billion light-years
The comoving distance from Earth to the edge of the observable universe is about 14.26 gigaparsecs (46.5 billion light-years or 4.40×1026 m) in any direction.

What if Earth was the size of the Milky Way?

Larger Scales Our own Milky Way galaxy, which is home to hundreds of billions of stars is estimated to be about 125,000 lightyears in diameter (and the latest research suggests it may be much larger). If Earth was the size of a grain of sand, the Milky Way would still be unimaginably huge, around 46,375,000km wide.

How small is Earth in the galaxy?

Answer: Assuming a diameter for the Milky Way galaxy of about 15 kpc, which is about 4.6×10^(17) km, and a diameter for the Earth of about 12756 km, the ratio of the diameter of the Milky Way galaxy to that of the Earth is about 3.6×10^(13).

Where is the Milky Way compared to Earth?

Earth is in the second largest galaxy of the Local Group – a galaxy called the Milky Way. The Milky Way is a large spiral galaxy. Earth is located in one of the spiral arms of the Milky Way (called the Orion Arm) which lies about two-thirds of the way out from the center of the Galaxy.

How many light years across is the Milky Way?

The Local Group is about 10 million light-years across, and the Andromeda galaxy is the most massive galaxy in it, The Milky Way is the second-most massive. The Milky Way is almost 1.5 trillion times the mass of the Sun.

What does the Milky Way galaxy look like?

The Milky Way galaxy is an immense, flat, disk-shaped collection of gas, dust, and stars that spreads around 100.000 light-years across and is several thousand light-years thick. There are at least 100 billion galaxies in the universe, and the Milky Way is just one of them.

What is at the galactic center of the Milky Way?

In the galactic center lays Sagittarius A*, a supermassive black hole that has a mass of about 4.3 million that of our Sun. This is a common feature of the galactic centers of galaxies. Sagittarius A* is about the size of Mercury’s orbit – 22.5 million km / 14 million mi.

How big is the stellar disk of the Milky Way?

Its stellar disk is approximately 100.000 light-years / 30 kpc in diameter. It is approximately 1.000 light-years / 0.3 kpc thick. The Local Group is about 10 million light-years across, and the Andromeda galaxy is the most massive galaxy in it, The Milky Way is the second-most massive.
