Lambda Arietis
What is Lambda Arietis
λ Arietis shines yellow-white at 129 light-years, set on one flank of the small zodiacal Ram. An F-class star, slightly hotter than the Sun and therefore slightly whiter, it lives a slightly shorter life. It belongs to the modest handful of stars that sketch Aries — few, discreet, yet enough for the Sun to cross them each spring along its apparent path on the ecliptic.
