Two new transits added to the Exoplanet Transits page

Two new exoplanet transits (TOI-1811b and Qatar-6b) has been added to the Exoplanet transits page.

More information about exoplanets and all the transits recorded here.

New exoplanet transit: XO-2Nb

XO-2Nb is a gas giant exoplanet orbiting XO-2N, an G9/K0V type star with an apparent magnitude of 11.14 and a size close to that of our Sun (Mass = 0.96 Msun, Radius = 0.998 Rsun).

Located in the constellation Lynx, it is 486 light-years away from us and takes only 2.6 days to complete one orbit around its star. Its discovery was announced in 2007. 

Its mass is 0.62 times that of Jupiter, and the distance to its star is 0.0368 AU.

Transit taken remotely on 11/01/2025 (with Moon at 95%) with TOA-150 telescope and STL-11000M camera (100 120-second exposures)
