Asteroid 4877, Humboldt, was discovered on September 25, 1977 by C.J. Van Houten and Ingrid Van Houten-Groeneveld at Leiden, Netherlands. It has a period of 4 years, 99 days.
Humboldt was named for globe-trotting German explorer and scientist Friedrich Wilhelm Heinrich Alexander Freiherr von Humboldt (1769–1859), whose ambition it was to collect and write down all there was to be known.
Alexander von Humboldt
Astrologically, asteroid Humboldt seems to indicate Alexander von Humboldt's burning passion: the thirst for knowledge.
Stephen Hawking has Humboldt sextile Mercury (thought, writing, speaking) and trine Pluto (unforgettable).
Astronomer, science popularizer and rationalist Carl Sagan had Humboldt conjunct the North Node, sextile Vesta (dedication, commitment) and Lilith (to marginalize or deal with reluctantly), square Mercury, Jupiter (philosophy, religious belief) and Pallas (conceptualization), and opposite the South Node (past experiences, taking in, separation).
Controversial Italian reproductive specialist Severino Antinori, whose clinic has helped numerous women in their fifties and early sixties give birth to babies and who has allegedly pursued research into reproductive cloning, has Humboldt in the first house, on the Ascendant, conjunct Jupiter and semisextile Chariklo (to glamorize, need to keep perspective).
Jesse Lazear (born May 2, 1866, in Baltimore) was a US Army medical researcher who died of yellow fever after allowing himself to be bitten by mosquitoes in order to (successfully, as it turned out) test a theory that mosquitoes were responsible for spreading the disease. He had Humboldt sextile Chaos (groundbreaking), Varuna (to grow big) and Phaethon (gone off course, beyond one's control), square Juno (giving up one's power), trine Uranus (unusual, innovative) and quincunx Ceres (to nurture).
Explorer Hiram Bingham (born November 19, 1875, in Honolulu), who discovered the lost city of Machu Picchu in Peru for the world at large, had Humboldt trine Chaos and opposite Mercury.
18th-century British explorer and naturalist Joseph Banks (born February 13, 1743 in London) had Humboldt conjunct Heracles (to strive with), semisextile Don Quixote (travels) and quincunx Mars (energy) and Hidalgo (to promote, to assert).
Undersea explorer Robert Ballard (born June 30, 1942, in Wichita) has Humboldt trine Chiron (the door-opener) and Dioretsa (something that sticks).
Alexander von Humboldt himself (who was born September 14, 1769 in Berlin) had Humboldt conjunct Venus (values, associating) and Okyrhoe (listening to oneself), semisextile Neptune (visionary, under an illusion), undecimal Pallas, and square Uranus.
The glyph for Humboldt is mine.
