1986 Halley's Comet
Halley’s Comet is one of the most famous periodic comets in the Solar System. It is named after the English astronomer Edmond Halley, who predicted its return after studying observations from earlier centuries. The comet orbits the Sun approximately every 75–76 years, making it visible to the naked eye about once in a human lifetime. Its most recent appearance was in 1986, and it is expected to return in 2061.
To commemorate the return of Halley’s Comet, the Philippines issued a set of two postage stamps on September 25, 1986. The 1-piso stamp (Scott #1922) depicts the comet and Earth, while the 2.40-piso stamp (Scott #1923) depicts the comet, the Moon, and Earth.
The 2.40-piso stamp was later overprinted in gold and revalued to 1.90 piso (Scott #1942) on August 1, 1988.
