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.

Consider the closest star system is alpha centauri, a little more than 4 light years away. If we split the difference, for 2 light years, you are in our solar system (at most), after that you must be out. If you are heading toward Alpha Centauri, you are now in their solar system. Otherwise you are in space as empty as that between John Kerry's ears.

It takes it 4 years to get to the nearest star, alpha-Centauri. Hence, alpha-Centauri is 4 light years away.
