MATHS BREAK!

Alpha Centauri is 4.37 light-years from Earth. Or 1596 light-days. How did we get that number? Well, 0.37 of a year is 135.05 days, and 365.25 x 4 + 135 = 1596). We needed the 0.25 because 2020 is a leap year! And 0.05 of a day is one hour and 12 minutes. See the boxout on Time for why this is so hard…
