What is Lambda Pegasi

Lambda Pegasi sits south of Pegasus's head, where the winged horse leans toward the celestial equator. It is a yellow G-type giant whose light has been travelling for more than 365 years before touching our eyes —as many as the Gregorian calendar has been counted. It belongs to the lattice of middle-magnitude stars that give body to one of the oldest, most recognisable constellations of the northern hemisphere.

Where it is and when to see it

Lambda 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 September, when it culminates around midnight.

From London it culminates about 62° above the horizon.
From New York it culminates about 73° above the horizon.
From Sydney it culminates about 33° above the horizon.

It can be seen from anywhere north of 66° S.
