Its story

Catalogued as 7 Ceti by John Flamsteed in the eighteenth century, this red giant has sent its light across 447 light-years to reach us. Its cool M-type surface beats with a slow variability that betrays the late chapter of its life. It glows along the northern flank of Cetus, the cosmic Whale, where the autumn sky opens onto fainter constellations —a russet point that only clean nights deliver.
