Planetary system

A semi-Jovian planet, WASP-11b/HAT-P-10b (WASP-11 A b/HAT-P-10 A b), was detected around the primary star independently by the Hungarian Automated Telescope Network and the Wide Angle Search for Planets teams both of which used the transit method.[3][9]

gollark: Again, dynamic DNS access token thingy?!
gollark: Unless I portforward polaris.apionet.irc (the one on the HNode™).
gollark: You don't have an IRC server though?
gollark: I just require a dynamic DNS token.
gollark: As I said, I can make helloboi.tk itself work probably maybe.
