1 lightyear is about 9.5 million km.
Not true. 1 lightyear is about 9.5 x 10^12 km. that is 9.5 TRILLION km
I'll show you why: light moves at 3 x 10^8 m/s. meaning every second it will travel 300 thousand km. now there are 31 556 926 seconds in a year. So, 300 000 x 31 556 926 = 9.467 x 10^12 km
new answer;
9.46 trillion
I get 9,460,730,472,581 km
