WASP-34 is a sunlike star of spectral type G5V that has 1.01 ± 0.07 times the mass and 0.93 ± 0.12 times the diameter of the Sun. It rotates on its axis every 34 ± 15 days, indicating it is around 6.7 billion years old.[2]
It has a planet 0.59 ± 0.01 times as massive as Jupiter that takes 4.317 days to complete an orbit.[2]
There is increasing evidence that there is a massive object orbiting the system further out.
Naming
In 2019 the IAU announced that WASP-34 and its planet WASP-34b would be given official names chosen by school children from The Philippines. [3][4]
