How many light years are we from the center of the Milky Way?

25,000 light years
Our solar system is in the Orion arm, and we are about 25,000 light years (2.5 X 10^17 miles) from the very center of the Galaxy. Since our solar system lies in one of the spiral arms, we live in the flat plane of the Milky Way.

How long would it take for light to leave the center of the Milky Way galaxy to reach Earth?

The disk of our home galaxy – the Milky Way – is bigger than we previously thought. 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.

Could we see a galaxy that is 20 billion light years away could we see a galaxy that is 20 billion light years away?

Average distances between galaxies are increasing with time. Could we see a galaxy that is 20 billion light-years away? (Assume that we mean a “lookback time” of 20 billion years.) No, because it would be beyond the bounds of our observable universe.

How many light years is the edge of the galaxy?

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 far is the nearest black hole?

1,500 light-years
Now, astronomers have discovered a black hole with just three times the mass of the sun, making it one of the smallest found to date—and it happens to be the closest known black hole, at just 1,500 light-years from Earth.

What is the ratio of one astronomical unit to one light year?

One Astronomical unit is the distance between earth and the Sun. That is 14,95,97,871 kilometres.One light year is the distance travelled by light in one year and that is equal to 9.461×10^12 kilometres.For the ratio… 149597871 : 9.461×10^12 that is approximately

What does the color of the Stars in an elliptical galaxy indicate?

• Red-yellow color indicates older star population. • Elliptical galaxies are much more common in huge clustersof galaxies (hundreds to thousands of galaxies).

What is the length of a light year in kilometers?

That is 14,95,97,871 kilometres.One light year is the distance travelled by light in one year and that is equal to 9.461×10^12 kilometres.For the ratio… 149597871 : 9.461×10^12 that is approximately An astronomical unit is the distance from the Sun to planet Earth – or about 93 million miles.

Are stars orbiting something massive but invisible?

• Stars appear to be orbiting something massive but invisible a black hole? • Orbits of stars indicate a mass of about 4 million MSun. • Our deepest images of the universe show a great variety of galaxies, some of them billions of light-years away. • A galaxy’s age, its distance, and the age of the universe are all closely related.
