What is Algieba

Algieba marks the mane of the celestial lion, an orange giant blazing 130 light-years away. Its name comes from the Arabic «al-jabha», 'the forehead', though medieval translators placed it on the mane by mistake — and there it has stayed. Through a small telescope it reveals itself as a striking system: two golden suns locked in a slow waltz no naked eye can untangle.

Where it is and when to see it

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

  • From London it culminates about 58° above the horizon.
  • From New York it culminates about 69° above the horizon.
  • From Sydney it culminates about 36° above the horizon.

It can be seen from anywhere north of 70° S.

It ranks no. 2 in brightness among the 80 stars of Leo in our catalogue. To find it, start from Regulus, the brightest: it lies about 8° away (a fist at arm's length covers about 10°).

The light you see today left it about 130 years ago.
