XO-6 is a faint 10th magnitude star in the constellation Camelopardalis.[1] Due to that apparent magnitude, this star is too faint to be seen with the naked eye, but can be seen with a telescope.[2]
Properties[edit]
This is a F-type main-sequence star with about 1.5 times the mass of the Sun. It is also radiating 4 times the luminosity, and is almost twice the size of the latter. It is also hotter, with a temperature of 6720 degrees Kelvin, which gives it the typical hue of an F-type star.[3]Unlike other stars of it's kind, this star is a rapid rotator, with a rate of 43 km/s.
Planetary System[edit]
In 2016, an enormous Hot Jupiter was discovered orbiting the star by the XO Telescope.
