* 1 AU (Astronomical Unit) is approximately 149.6 million kilometers.

* To find the distance in kilometers for 1.5 AU, multiply the distance of 1 AU by 1.5:

149.6 million km * 1.5 = 224.4 million kilometers

Therefore, a moon discovered at 1.5 AU from the sun would be approximately 224.4 million kilometers away.
