What is HIP 102431

In Cepheus —the king chained to the polar sky— burns a yellow-white F-type star, slightly hotter than the Sun. Its light set out eighty-nine years ago, when in 1937 Amelia Earhart vanished over the Pacific and the world held its breath beside the radio. That same flicker, faithful to its rhythm, arrives now —untouched— to whoever turns their gaze northward.

Where it is and when to see it

HIP 102431 lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is September, when it culminates around midnight.

  • From London it never sets and culminates about 84° up.
  • From New York it never sets and culminates about 73° up.
  • From Sydney it never rises above the horizon.

It can be seen from anywhere north of 32° S.

It ranks no. 16 in brightness among the 95 stars of Cepheus in our catalogue. To find it, start from Alderamin, the brightest: it lies about 6° away (a fist at arm's length covers about 10°).

The light you see today left it about 89 years ago.
