The Milky Way galaxy is about 100,000 light-years in diameter. If we assume an average commercial airplane speed of around 900 kilometers per hour (560 miles per hour), it would take approximately 1.6 billion years to cross from one side of the galaxy to the other. This immense time frame highlights the vastness of our galaxy compared to human scales of distance and time.
It takes about 13.99 billion years for a galaxy to form.
Each individual object (such as a star) revolves around the galactic center according to the laws of celestial mechanics. As a result, the objects closer to the center of the galaxy take less time for a complete revolution than the objects further out; the galaxy rotation is differential, meaning it does not rotate as if it were a solid object.
