How long would it take to leave the Milky Way galaxy?
So, to leave our Galaxy, we would have to travel about 500 light-years vertically, or about 25,000 light-years away from the galactic centre. We’d need to go much further to escape the ‘halo’ of diffuse gas, old stars and globular clusters that surrounds the Milky Way’s stellar disk.
How long would it take to cross the Milky Way in light years?
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.
How long would it take us to get to the nearest galaxy in light years?
approximately 749,000,000 years
To get to the closest galaxy to ours, the Canis Major Dwarf, at Voyager’s speed, it would take approximately 749,000,000 years to travel the distance of 25,000 light years! If we could travel at the speed of light, it would still take 25,000 years!
Can we go to another galaxy?
The technology required to travel between galaxies is far beyond humanity’s present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.
How long does it take to leave our solar system?
At its current speed, it will take roughly 15,000 years to cover one light year and will take about 40,000 years before the Voyagers come close to another star.
How many light years away is the Milky Way?
It depends on whereabouts you want to get to; our vast Galaxy is thousands of light-years across, but for a decent vantage point you would need to travel much further. Our Galaxy, the Milky Way, is a disk of stars about 100,000 light-years across, and about 1,000 light-years thick.
How long would it take Voyager to travel across the Milky Way?
At this speed, the probe is capable of traversing a distance of one light year in about 20,000 years. To cross the Milky Way at this speed, Voyager would have to travel for around 2 billion years.
How many light years away is the Earth?
The galaxy is about 100,000 light-years across, and the Earth is about 28,000 light-years from its center.
How often does the Sun rotate around the Milky Way?
At our sun’s distance from the center of the Milky Way, it’s rotating once about every 225-250 million years – defined by the length of time the sun takes to orbit the center of the galaxy.
