... will live and die in one year on this planet (if it were habitable). Check the orbital period and semi major axis values.

Approximately 50k Ls far from it's parental neutron star. I have found this insanity on my two months long trip to Sag A (still 8k Ly to go). Checked with Universal Cartographics webpage if it is a record - and nope, the record is 130AU semi major axis and 1 mil. days orbital period for a HMC planet.

CMDR DancingLemur out.

Our own Pluto is about a quarter of that, which I still find impressive.

Speaking of orbital stats - I prepared the pub quiz a couple of weeks ago. One of my tie breaks was "If the Earth was shrunk to the size of a snooker ball, Neptune would be as big as a size five football. How far apart would they need to be to represent the difference in their average orbital radius?"

Thankfully it wasn't needed in the end

Think there might be a "winter is coming" joke somewhere in here...
Although 196 k is pretty freaking cold (-77c) even here in Norway ;)

It was what inspired the question :)

I had to scale it to something that the old folk in the pub would be able to visualise, hence the snooker ball and football.
