By arbitrary definition, a brown dwarf's lower limit is 10X the mass of Jupiter. This star- free planet is less than that, so by definition it is a planet and not a star.

I received a call from a fellow who is planning on going to SPOC tomorrow night and would like to see Neptune and Uranus. Is anyone going who can show him? Are the two planets even viewable? -A

I believe Jupiter radiates more energy than it receives from the sun. Probably the rogue planet does the same.

A giant planet lost-in-space! This is the first time that I can think of where astronomers found one so close to us. Neat pic with the article as well. http://www.nbcnews.com/science/astronomers-say-theyve-spotted-lonesome-plan… Tom Sevcik

Re: [Utah-astronomy] Star party at Tintic High School

I've contacted Greg Thornock. Tintic HS, btw, is in Eureka. And if you can pronounce that and Toole like a native; you pass native muster ;-) It's about an hour's drive for me, but it sounds like it could be fun. If anyone for Utah County wants to go along, I'll put the word out when we have some dates and go/no-go times determined. Ciao, John
