How does an astronomical unit compare to km
WebThe planet moves faster when it's closer to the Sun P^2 = P^3, and we know a = 1.52 AU, so a times a times a is 3.51 So P^2 = a^3 and a^3 = 3.51 in this case. So P^2 = 3.51. What is P? 1.87 years What was Kepler's First Law?

WebDec 8, 2024 · When we talk about the distances to the stars, we no longer use the AU, or Astronomical Unit; commonly, the light year is used. A light year is the distance light travels in one year - it is equal to 9.461 x 10 12 km. Alpha Centauri A & B are roughly 4.35 light years away from us. Proxima Centauri is slightly closer at 4.25 light years.
