The Dolphin Nebula, also known as Sh2-308, is a fascinating celestial structure located approximately 4,500 light-years away. This nebula is shaped by the powerful stellar winds from its central star, a Wolf-Rayet star (EZ Canis Majoris, WR 6) …Read more
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.
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)

XO-7b is a gas giant exoplanet orbiting XO-7, an G0V- type star with an apparent magnitude of 10.5 and a size close to that of our Sun (Mass = 1.40 Msun, Radius = 1.48 Rsun).
Located in the constellation Ursa Minor, it is 764 light-years away from us and takes only 2.9 days to complete one orbit around its star. Its discovery
was announced in 2019.
Its mass is 0.726 times that of Jupiter, and the distance to its star is 0.0432 AU.
