apparent magnitude of 4.8, was the brightest star in the constellation, Bode assigning it the designation 'a'. Located 420 ± 20
light-years distant from Earth, it is an orange giant of spectral type K3III. Other stars belonging to the constellation include
ψ4,
ψ5,
ψ7,
ψ8,
ψ9,
63,
64,
65 and
66 Aurigae, and

ψ5 Aurigae is a sunlike star of spectral type G0V that is around 1.07 times as massive as the Sun and 1.18 times as wide. It appears to have a circumstellar disk of dust, known as a
debris disk. Bode also gave them Bayer designations from a to p, also adding an uppercase B, although after the constellation was declared obsolete they were disused. Here is a table of stars with the corresponding Bayer designations. == See also ==
