WASP-26 is a G-type subgiant star about 824 light-years away in the constellation of Cetus.

Kelu-1 is a system of two brown dwarfs of spectral types L2 and L4 located in constellation Hydra at approximately 60.6 light-years from Earth. It is among the first free-floating later-than-M-type brown dwarfs discovered, and sometimes considered as prototype of L-type brown dwarfs.

Type of variable star

KELT-2 (also called HD 42176) is a binary star located about 439 light-years away in the constellation Auriga. The apparent magnitude of the system is 8.68, which means it is not visible to the naked eye but can be seen with binoculars. The system is moving towards the Sun at over 40 km/s.

WASP-45 is a K-type main-sequence star about away. The star's age cannot be well constrained, but it is probably older than the Sun. Yet WASP-45 is enriched in heavy elements compared to the Sun, having 240% of the solar abundance. WASP-45 has low ultraviolet emission, therefore it is suspected to have a low starspot activity, although chromospheric activity was reported elsewhere.
