What is HIP 1191

In the vast Whale burns a blue-white B-type star, whose surface exceeds ten thousand degrees. Its light crossed three hundred thirty-nine years to reach us, departing around 1687, the year Newton published his Principia Mathematica in London and refounded modern physics. Hotter, more massive, and far more luminous than the Sun, it lives a brief and dazzling existence, leaving its bluish mark upon the silent back of Cetus.

Where it is and when to see it

HIP 1191 lies in the southern 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 culminates about 29° above the horizon.
  • From New York it culminates about 40° above the horizon.
  • From Sydney it culminates about 66° above the horizon.

It can be seen from anywhere south of 80° N.

It ranks no. 84 in brightness among the 111 stars of Cetus in our catalogue. To find it, start from Diphda, the brightest: it lies about 11° away (a fist at arm's length covers about 10°).

The light you see today left it about 340 years ago.
