XO-6b is a transiting exoplanet, orbiting the star XO-6 around 760 light years (230 parsecs) away from Earth. It was discovered in 2016 by the XO planet search team.{{Cite encyclopedia |date=2016 |title=The Extrasolar Planet Encyclopaedia — XO-6 b |url=https://exoplanet.eu/catalog/xo_6_b--4076/ |access-date=2021-02-18 |encyclopedia=Extrasolar Planets Encyclopaedia}}

Characteristics

XO-6b is classified as a hot Jupiter. The planet has an orbital period of just 3.8 days and an average orbital separation of 0.082 astronomical units. As of such, it is highly irradiated, with a surface temperature estimated to be around {{convert|1670|K|C}}. The planet's mass is estimated at {{val|1.73|0.20|ul=Jupiter mass}}. The discovery paper suggested a very large radius of {{Val|2.07|0.22|ul=Jupiter radius}}, which would make it among the largest known exoplanets, but more recent papers, considering the measurements of the host star's distance by the Gaia satellite, found the radius to be smaller, at around {{Val|1.5|u=Jupiter radius}}.

XO-6b orbits XO-6, a faint 10th magnitude star in the constellation Camelopardalis.{{Cite constellation|BD+73 323}} Due to its magnitude, this star is too faint to be seen with the naked eye, but can be seen with a telescope.{{Citation needed|date=February 2024}} XO-6 is a F-type main-sequence star with about 1.30 times the mass of the Sun. It is also radiating three times as bright, and is 1.4 times the size of the Sun. It is also hotter, with a temperature of {{val|6724|ul=K}}, which gives it the typical hue of an F-type star. Unlike most other stars of its kind, XO-6 rotates rapidly at a rate of 43 km/s.{{Citation needed|date=May 2025}}
