What is Tejat

Tejat is a red giant variable in Gemini, 231 light-years away, cool and enormous as almost all stars at the dusk of their lives. Its name comes from Arabic and is associated with the idea of treading, in allusion to the foot of the twin Castor. Its brightness breathes with the slowness of months; each pulse is a layer of hydrogen fused in its ancient heart.

Where it is and when to see it

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

  • From London it culminates about 61° above the horizon.
  • From New York it culminates about 72° above the horizon.
  • From Sydney it culminates about 34° above the horizon.

It can be seen from anywhere north of 67° S.

It ranks no. 5 in brightness among the 74 stars of Gemini in our catalogue. To find it, start from Pollux, the brightest: it lies about 19° away (a fist at arm's length covers about 10°).

The light you see today left it about 230 years ago.
