In terms of hospitality?
So HD 189733b is probably a planet you wouldn't want to be on.
Located about 64.5 light-years from Earth, this planet is about 13% larger than Jupiter.
Besides, it can hold a little over 1400 Earths, and it has a pretty hot temperature of around 1800°C (3272°F) at times. To give you some perspective, iron melts at 1535°C or 2795°F, so you don't stand much chance of survival.
And that's not the most interesting part about this exoplanet.
If you happen to survive its extremely hot atmosphere, then you will be able to experience another of its main attributes: the wind speed.
With a speed of approximately 5,400 miles per hour (8,690 km/h), its wind speed is the fastest recorded on any planet. The wind is capable of reaching seven times the speed of sound.
The best part is that the winds bring silicate particles and sometimes it rains molten glass.
In short, HD 189733b is a place you wouldn't want to be.
