   Galactic year. The galactic year, also known as a cosmic year, is the duration of time required for the Sun to orbit once around the center of the Milky Way Galaxy. [1] One galactic year is approximately 225 million Earth years. [2] The Solar System is traveling at an average speed of 230 km/s (828,000 km/h) or 143 mi/s (514,000 mph) within its ...

   Answer: Yes, the Sun - in fact, our whole solar system - orbits around the center of the Milky Way Galaxy. We are moving at an average velocity of 828,000 km/hr. But even at that high rate, it still takes us about 230 million years to make one complete orbit around the Milky Way! The Milky Way is a spiral galaxy.

   How long does it take to reach the Milky Way?

   • At the sun's current speed, it takes around 230 million years for our home star to complete one trip around the Milky Way. That is longer than dinosaurs walked the Earth and more than 750 times longer than humans ( Homo sapiens) have existed.

   Could a spaceship travel across the Milky Way?

   • 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. Researchers made the find after analyzing the abundances of metals (heavy elements) in stars, also known as their metallicities.

   How far away is the Sun from the Milky Way?

   • The Milky Way is about 1,000,000,000,000,000,000 km (about 100,000 light years or about 30 kpc) across. The Sun does not lie near the center of our Galaxy. It lies about 8 kpc from the center on what is known as the Orion Arm of the Milky Way. Parallaxes give us distances to stars up to perhaps a few thousand light years.

   Oct 22, 2020 · If it could travel at the speed of light, an impossibility due to Special Relativity, it would still take over 26,000 years to arrive! At 17.3 km/s, it would take Voyager over1,700,000,000 years to traverse the entire length of the Milky Way. Even traveling at the speed of light, it would take nearly a hundred thousand years! Back
