HIP 77858
Hot blue starWhat is HIP 77858
In the stinger of the Scorpion burns a class B sapphire whose light crossed 420.4 years to reach us. It departed around 1605, the year Cervantes published the first part of Don Quixote and opened a new era for the European novel. A blue surface, intense, far hotter than the solar one —a high note in the basso continuo of the firmament.
