1 light year =5.85 trillion miles=5.85E12 & 1 Astronomical Unit =92.5 million miles=92.5E6. Therefore, the distance to Proxima Centauri is 4.22 times 5.85 trillion miles divided by 92.5 million miles per Astronomical Unit =4.22X5.85E12/92.5E6=267,000 Astronomical Units=2.67E5 Astronomical Units to Proxima Centauri. This is over a quarter million times the distance between the sun & earth! Cool! My slide rule wasn't too far from Surveyor's calculator.

properly.. one astronomical unit is the final distance between the earth and the sunlight. we've a planet in our image voltaic gadget that's sort of two AUs from the sunlight, Mars, which takes sort of two years to orbit the sunlight, so determination 4 is out. we've a bunch of debris in orbit around the sunlight at sort of four AUs, talked approximately as the asteroid belt, so, all we actually could do is locate out how long their orbits are. We additionally hava a planet, Jupiter, that's 5.2 AU out, whose orbit is approximately 12 years, so, sixteen is out. So, i might bypass with determination variety 3, that's 8 years.

1 light year [tropical] = 63 239.726 348 916 astronomical unit.
4.22 light year [tropical] = 266 871.645 192 425 astronomical unit.
1 light year [Julian] = 63 241.077 088 071 astronomical unit.
4.22 light year [Julian] = 266 877.345 311 659 astronomical unit.
1 light year [traditional] = 63 197.790 929 9 astronomical unit.
4.22 light year [traditional] = 266 694.677 724 177 astronomical unit.

Is anyone else tempted to give the wrong answer to people who expect someone else to do their homework for them?
My answer is
4.22 ly x (45 liters/ly) x (1 AU/1.63x10^44 liters) = 8.27 x 10-44 AU.
But it's really a trick question because it depends on what time of day you measure how much water is in a liter.
