The nearest star to Earth is Lacaille 9352 which is roughly about 10.68 Light Years from the Earth. The nearest star to the Earth with an exoplanet is Fomalhaut which is about 25.13 Light Years. The furthest star that can be located in the constellation is HIP 106229 which is located about 81540.8 Light Years away from the Sun. The furthest figure is derived from either the 1997 or 2007 Hipparcos star catalogue parallax figure and it has been known to produce distances that are wrong.

The caveat of these stars are that they are catalogued on this site. If you know of a star that is nearer or further then do let me know in the comments and I'll add it to the site. The stars mentioned are from the Hipparcos catalogue or have been added because of their special status.
Was the mother of Pisces. The Goddess Derecto was forced to marry a mortal by Aphrodite. After conceiving a daughter Semiramis, the spell wore off and she became a Goddess again. Derecto killed her daughter and jumped into the river therefore transforming herself into the Southern Fish.
The bright star Fomalhaut is one of the earliest stars that scientists believe could have an orbit planet. It is a southern constellation and one that is known for its meteor shower in August albeit a not so bright one.

As there's so many stars in the cosmos, not all the stars are listed here. The site has lots of stars not listed so if your star isn't listed and you know the Henry Draper or Hipparcos ID, type https://www.universeguide.com/star/ then followed by the HIPNNNNNN or HDNNNN where NNNNN is the number part of the name. The stars that I do list have either a traditional name, a bayer or other classification name.
