Historical character

 

The asteroid Alexandra is named after the naturalist and astronomer Alexander von Humboldt (1769-1859), especially recognized for setting the foundations of the discipline 'biogeography', which studies the distribution of species and ecosystems throughout geographic space and geological time.

 

Distribution of the world population today

The asteroid Alexandra is related with the ability to assess the social environment of a determined urban, rural or geographical area, depending on the moment of the diurnal and annual cycle.

Dian Fossey, zoologist recognized for her scientific work and for the protection and conservation of gorillas in the Virunga Mountains, in Rwanda and the Democratic Republic of the Congo, has Alexandra in Cancer (9th Moon-Node House, cusp), in opposition to Mars; in quincunx with Vesta in Aquarius (2nd Moon-Node House, cusp) [which is in conjunction with Venus]; and in trine with the Moon Node in Pisces and with the Crossing Point of Age Progressions in Pisces [which are in conjunction with the Aries point].

 

Sigourney Weaver, actress of the movie "Gorillas in the Mist" (1988), has Alexandra in Leo (9th Moon-Node House), in trine/sextile with the Crossing Axis of Age Progressions in Aries/Libra [which is conjunct Mercury in Libra (7th Moon-Node House) and in square with Uranus in Cancer (10th Moon-Node House)].
