Outdoor Solar Lights

Easy one you just take the distance of the newly discovered planet (Xena, also called Sedna) and divide it by the speed of light.
That is 8400 million km divided by 300000 km/sec and that

= 84000/3
= 28000 seconds
If you want it in minutes then,
= 28000/60
= 2800/6
= 466 minutes and 40 seconds
Earth takes only 8.5 minutes to recieve the rays.
