There are 7 main stars in that system. But many minor stars are there also, as it spans hundreds of light years.
GJ 3379 is considered within the constellation, and at 17.5 ly is the closest:
Epoch J2000.0
Equinox J2000.0
Right ascension 06h 00m 3.495s
Declination +02° 42′ 23.67″
If the RST is correct, most of the main stars are very old (blue).
