What else can I help you with?
How long would it take to cross the milkyway at an impossible speed of light?
About 100,000 years. (the diameter of the Milky Way galaxy is 100,000 light years)
What is the distance across the Milky Way?
The Milky Way is approximately 100,000 light-years in diameter. This means that if you could travel at the speed of light, it would take you 100,000 years to cross from one side of the galaxy to the other.
How long does it take light to cross the diameter of your Milky Way Galaxy?
About 100,000 years
How many years would it take a spacecraft traveling at the speed of light to cross the milky way galaxy?
The very fastest human-made spacecraft ever aren't out of this solar system yet, and they were launched in the 70s."Billions of years" is, if anything, an understatement.
How long is the Milky Way in light years?
The Milky Way's diameter is about 100,000 light-years.
If the Sun and Earth were at the edge of the disk of the Milky Way Galaxy what would be the diameter of the galaxy in light years?
The diameter of the Milky Way galaxy is about 100,000 light-years. If the Sun and Earth were at the edge of the disk, we would still be within the galaxy's boundaries, so the diameter would remain around 100,000 light-years.
If you could travel at the speed of light how long would it take to travel from one side of the Milky Way galaxyto the other?
The Milky Way galaxy is about 100,000 light-years in diameter. If you could travel at the speed of light, it would take approximately 100,000 years to cross from one side of the galaxy to the other. However, this is a theoretical scenario, as current laws of physics suggest that nothing with mass can achieve the speed of light.
At light speed how fast does it take to cross the milky way?
About 100,000 years.About 100,000 years.About 100,000 years.About 100,000 years.
If a spiral galaxy is 7 billion light-years from Earth and its apparent size is 0.05 arcmin what would its diameter be?
25,000 light years (4 times smaller than the Milky Way).
How long would it take a ray of light to travel from the sun to the edge of our galaxy the milky way?
The Milky Way galaxy is about 100,000 light-years in diameter. Since light travels at a speed of approximately 299,792 kilometers per second, it would take a ray of light about 100,000 years to travel from the sun to the edge of the Milky Way.
How long does it take the Milky Way to rotate?
A disk has multiple speeds - at it's perfect center it's standing still (as you approach the center the speed gets smaller and smaller as you approach 0) At the outer rim (where our star Sol and it's attending planets) are rotating around the galaxy center at about 500,000 mph, ~0.0007% of the speed of light.
How far across the milky way?
The Milky Way is about 100,000 light years in diameter and about 1000 light years thick.
