HR 2094
Scientific overview
HR 2094 is a main-sequence star in the constellation Pictor (Pictoris), lying about 113.17 light-years from Earth.
Class F. Yellow-white stars, somewhat hotter and more massive than the Sun. Such stars have surface temperatures around 6,000–7,500 K and appear yellow-white to the eye.

Evolution
A main-sequence star fuses hydrogen into helium in its core. It will remain on the main sequence for most of its life before evolving into a giant.
