887 Alinda (// ə-LIN-də) is a very eccentric, near-Earth asteroid with an Earth minimum orbit intersection distance (MOID) of 0.092 AU. It is the namesake for the Alinda family group of asteroids and measures about 4 kilometers in diameter. The stony S-type asteroid was discovered by German astronomer Max Wolf at Heidelberg Observatory on 3 January 1918.
Due to its high eccentricity and semi-major axis of 0.57 and 2.5 AU, respectively, it is a typical Amor III asteroid. It has both, a 1:3 orbital resonance with Jupiter and a close to 4:1 resonance with Earth. In addition, because its orbit also lies within the asteroid belt, it is often classified as a main-belt asteroid.
The asteroid's name had been proposed by H. Kobol. It is uncertain whether it refers to the ancient city of Alinda in modern western Turkey, or to a mythological figure of the Australian aboriginals.
