This is the distance that light travels in a year, so 1 light year is about 9,500,000,000,000 km. Using this unit, we say that the star Proxima Centauri is about 4.2 light years away. Even using this unit, numbers in space get pretty big. WebApr 22, 2024 · How do we measure distances in space? Lightyears. A common method for measuring distance in space is to measure how far light travels in one year: known as a lightyear, which is around 9.5 trillion km. If you want to be precise, the IAU regards a year as 365.25 days, making a lightyear 9,460,730,472,580,800m. daisy\\u0027s third eye
