It just seems impossible for humans to boldly go where no one has gone before! The Canis Major Dwarf Galaxy is a mere 25,000 light-years from us and 42,000 light-years from the galactic center. Interestingly, though, there is another galaxy closer to our solar system than our galactic center. Light travels 186,000 miles per second.Īt lightspeed, it would be a four year trip from the Earth to Alpha Centauri, the star system closest to ours.Įven more extreme, to reach the galactic center of our own Milky Way would require 30,000 years of lightspeed travel. Just to clarify an astronomical unit is 93.0 million miles-the average distance from the center of the earth to the center of the sun and a light-year is the distance that light travels per year, which is about 6 trillion miles. Travel at the speed of light takes years, decades, centuries, even millennia to transit the space between neighboring stars, let alone galaxies. Ron Hubbard, To the StarsĪstronomical units and light-years are depressingly small units in describing the distances. “Space is deep, Man is small and Time is his relentless enemy.” -L.
