WASP-5
WASP-5 is a magnitude 12 yellow dwarf star located about 910 light-years away in the Phoenix constellation.[2] The star is likely older than Sun, slightly enriched in heavy elements and is rotating rapidly, being spun up by the tides raised by the giant planet on the close orbit.[3]

gollark: Because they've never really worked well, or at all, and also I'd rather not spread badly done OOP around.
gollark: ``` src idk 2 years ago static I have no idea what I'm doing 2 years ago templates idk 2 years ago uploads Wow. First Rust project done. 2 years ago Cargo.lock idk 2 years ago Cargo.toml idk 2 years ago Rocket.toml I have no idea what I'm doing 2 years ago```
gollark: Honestly it's not great (see the name...) but it'd take ages for me to make a nicer one.

gollark: It's his project, I think.
