(1685) Toro

(1685) Toro is a planetoid of the Apollo type.

The Earth-Near Asteroid was discovered on July 17, 1948 by Carl A. Wirtanen at the Lick Observatory on Mount Hamilton. Toro is named after the wife's birth name (Betulia Toro) by Samuel Herrick, an American engineer and astronomer who studied the orbit of this asteroid.

Toro moves between 0.77712 AU (perihelion) and 1.9630 AU (Aphel) in about 1.6 years around the sun. The orbit is inclined at 9.377 ° against the ecliptic, the eccentricity is 0.4359.

Toro is located in an interesting orbit in an 8: 5 resonance with the Earth on its own and a 13: 5 resonance with the Venus on the other hand. His path therefore takes him close to the earth every eight years.

Toro is classified as S-type and rotates its own axis in 10,196 hours. The albedo of its surface is 0.31 and its diameter is estimated to be about 3 kilometers. Edit source text
