Eta

Its story

A yellow-white F-type star at just 94 light-years away — one of the closest in Aries — with a nuclear metabolism only slightly more energetic than the Sun's and roughly six solar luminosities to its name. It is around 2.6 billion years old, two thirds of the Sun's age, with a radius twice ours. It sits in the zodiacal Ram whose spring equinox once fixed the origin of ecliptic coordinates, a reference point millennia ago that Earth's slow precession has long since shifted.
