Calculations involving light years and distance So 10 light years is around 58.79 trillion miles (94.61 trillion km). Our Sun is the closest star to us. For example, if we were to travel at a speed of 58,536 km / h, which is the speed at which the New Horizons rehearsal travels on its way to Pluto, it would take us just under 20,000 years to cross the path of one light year. One light year is equal to the distance that light travels in one year (it is about ten trillion kilometers, or six trillion miles). Exact Answer: 37,200 Years (Approx) Light-year is a unit of distance. Is time Travelling possible? If it was to take Voyager 70 years, including stops and detours to search for fuel and supplies, to travel 70k lightyears, it would take them almost a month to go 100 light years. Time has its own direction and follows the path to flow. 00006 the speed of light. From the light's perspective, it's very different, due to time dilation. If you want to swallow 1000s of Ly and have an extra bonus for doing so, you can take those long-range ones. A typical higher achievable speed for a spacecraft is on the order of 20 km/s, or around 15,000 years to travel one light-year. A light year is almost 6 trillion miles.
