Three more sets of observations of exoplanet transits for the ExoClock project by Simon Dawes. WASP-52b, Qatar-1b and HAT-P-6b.

WASP-52 b is a gas giant exoplanet that orbits a K-type star. Its mass is 0.46 Jupiters. Exoplanet WASP-52b orbits at a distance of 4.07 million km from its host star WASP-52, taking 1.75 days to go round its orbit. Its discovery in the constellation Pegasus was announced in 2012.


Qatar-1 b is a gas giant exoplanet that orbits a metal-rich K-dwarf star, which is one of the faintest around which a planet has been discovered by ground based surveys. Its mass is 1.294 Jupiters, takes 1.4 days to complete one orbit of its star and is 0.02332 AU from its star. Its discovery was announced in 2010.


HAT-P-6b was discovered on October 15, 2007.  It is located in the constellation Andromeda.  It takes 92 hours, 28 minutes, 17 seconds and 9 deciseconds to orbit its host star.  The planet HAT-P-6b is named Nachtwacht. The name was selected in the NameExoWorlds campaign by the Netherlands, during the 100th anniversary of the IAU, after Rembrandt’s painting The Night Watch.  It is one of the few planets that is in a retrograde orbit around its host star.
