What is the distance across the milky way galaxy?
Our Milky Way galaxy is 100,000 light years across.
How long does it take light to travel across the diameter of the Milky Way?
Approx 100000 to 180000 years.
Which galaxy is the Orion nebula in?
The Orion nebula is part of our own galaxy (the Milky Way). The Orion nebula is about 1500 light-years away from us. Our galaxy is about 100000 light-years across.
What is the distance across the milky way disk?
The Milky Way is about 100,000 light years across.
How many light years is the Milky Way across?
100,000 ly across but only about 1000 ly thick.
How many light years the galaxy to galaxy?
The nearest galaxy to our Milky Way is the Andromeda galaxy, which is about 2.5 million light years away (that is not including the Large and Small Magellanic Clouds, small, irregular "satellite" galaxies of our own).
How far across the milky way?
The Milky Way is about 100,000 light years in diameter and about 1000 light years thick.
At its nucleus the Milky Way Galaxy is about 100000 light-years wide and .?
The whole of the galaxy has a diameter of approx 100000 light-years, not just the nucleus! So it is not clear whether the question is about the galaxy or its nucleus.
What is the diameter of the Milky Way?
Approximately 100,000 light years across.
How wide is the milky way?
The Milky Way is approximately 100,000 light years across. The value may differ according to sources because the Milky Way does not have a defining boundary.
Is our local supercluster 50 million light years across?
The Virgo Supercluster (in which the Milky Way is located) is about 200 million light years across.
If it takes 100000 years for light to travel across the milky way how do you know that the star is even there when you see the light from it?
Quite simply, you don't. You see the star in the past - this may be 4 years in the past, in the case of Rigil Kentaurus, 30,000 years for a star in the center of our Milky Way, 2-3 million years in the case of the Andromeda Galaxy, or billions of years in the case of a quasar (the latter is not a star).
