100,000 years
Assuming you are referring to our Galaxy - The Milky Way. Light will take about 100,000 years to get from one side to the other.
The Milky Way galaxy is about 100,000 light-years in diameter. Therefore, if you could travel at the speed of light, it would take approximately 100,000 years to traverse from one side of the galaxy to the other. However, this is a theoretical scenario, as traveling at the speed of light is not currently possible according to our understanding of physics.
Traveling across the Milky Way galaxy at the speed of light would take approximately 100,000 years. However, with current technology, it is impossible for humans to travel at such speeds, so the actual time to traverse the galaxy would be much longer.
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.

About 100,000 years
our galaxy is called the Milky way. its approximately 100,000 light-years (9.5×1017 km) in diameter.
Uranus is within the Milky Way Galaxy.
Not long at all - as you/we are already in it. About 25,000 light years from the centre.
Depends witch star it comes from. The closest stars light will only take 7 years but most of the stars (that are relatively closeby compared to the light of other galaxies) will take 200 or more.
Mars (and every other planet in our solar system) is nowhere near the center of the galaxy. About 75,000 light years...

Between 100,000 and 180000 years.
