The exoplanet HD 209458b has a mass more than 200 times Earthт??s and has a diameter greater than Jupiterт??s. It orbits its star at about an eighth of the distance Mercury orbits the sun, so the exoplanet takes only 3.5 days to complete an orbit. This proximity to a star means that the planet is hot, perhaps 1000ТАC, hence it is classed as a т??hot Jupiterт?? ...

... The Virtual Impactor 2011 BA12 on 2011 February 8th. Images obtained using the Faulkes Telescope North, operated by Las Cumbres Observatory.
