What is 1 Pegasi

1 Pegasi leads Flamsteed's catalogue of the Winged Horse, an orange K-type giant burning some 156 light-years away. Its light, ruddier and calmer than the Sun's, set out toward us when movable type was still a European novelty. It glows in the northwestern corner of Pegasus, far from the Great Square, where the eye usually pauses before leaping toward the horse's head. A quiet lantern in a region many travellers cross without stopping.

Where it is and when to see it

1 Pegasi lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is August, 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.

The light you see today left it about 160 years ago.
