Capella Aa is the cooler and more luminous of the two with spectral class K0III; it is 78.7 ± 4.2 times the Sun's luminosity and 11.98 ± 0.57 times its radius. An aging red clump star, it is fusing helium to carbon and oxygen in its core.
Lambda Aurigae, Latinized from λ Aurigae, is the Bayer designation for a solar analog [9] star in the northern constellation of Auriga. [13] It is visible to the naked eye with an apparent visual magnitude of 4.71. [2] Based upon parallax measurements, it is approximately 40.7 light-years (12.5 parsecs) distant from the Earth. [14]
Messier 37 (also known as M37, NGC 2099, or the Salt and Pepper Cluster) is the brightest and richest open cluster in the constellation Auriga. It was discovered by the Italian astronomer Giovanni Battista Hodierna before 1654. M37 was missed by French astronomer Guillaume Le Gentil when he rediscovered M36 and M38 in 1749.
AB Aurigae is a young Herbig Ae star [3] in the Auriga constellation. It is located at a distance of approximately 509 light years from the Sun based on stellar parallax . [ 1 ] This pre-main-sequence star has a stellar classification of A0Ve, [ 4 ] matching an A-type main-sequence star with emission lines in the spectrum .
Messier 38 or M38, also known as NGC 1912 or Starfish Cluster, [4] is an open cluster of stars in the constellation of Auriga. It was discovered by Giovanni Batista Hodierna before 1654 and independently found by Le Gentil in 1749. The open clusters M36 and M37, also discovered by Hodierna, are often grouped together with M38. [5]

It is over 190,000 times more luminous, around 20 times more massive and around 70 times larger. Its surface has an effective temperature of 14,600 K . [ 5 ] It has a stellar wind that is causing mass loss at the rate of 0.38–0.46 × 10 −9 solar masses per year, or the equivalent of the Sun's mass every 2.4 billion years.
IC 405 (also known as the Flaming Star Nebula, SH 2-229, or Caldwell 31) is an emission and reflection nebula [1] in the constellation Auriga north of the celestial equator, surrounding the bluish, irregular variable star AE Aurigae. It shines at magnitude +6.0. Its celestial coordinates are RA 05 h 16.2 m dec +34° 28′. [2]
