94 Aquarii
Scientific overview
94 Aquarii is a subgiant in the constellation Aquarius (Aquarii), lying about 68.88 light-years from Earth.
Class G. Yellow stars like the Sun. On the main sequence they steadily fuse hydrogen into helium. Such stars have surface temperatures around 5,200–6,000 K and appear yellow to the eye.
