Alinda group (of asteroids) (218 words)
Some Alindas have perihelia very close to Earth's orbit, resulting in a series of close encounters at almost exactly four-year intervals, due to the 4:1 resonance.
One consequence of this is that if an Alinda asteroid happens to be in an unfavorable position for viewing at the time of its close approach to Earth (for instance, at a small elongation from the Sun), then this situation may persist for decades.
As of 2004, for example, the Alinda asteroids 1981 VA and (1915) Quetzalcoatl had not been observed since 1985, and (2608) Seneca had not been observed since 1994.
Alinda family - definition of Alinda family in Encyclopedia (246 words)
The Alinda asteroids are a group of asteroids with a semi-major axis of about 2.5 AU and an orbital eccentricity approximately between 0.4 and 0.65.
One consequence of this is that if an Alinda asteroid happens to be in an unfavorable position for viewing at the time of its close approach to Earth (for instance, at a small elongation from the Sun), then this situation can persist for decades.
Indeed, as of 2004, the Alinda asteroids (3360) 1981 VA and 1915 Quetzálcoatl had not been observed since 1985, and 2608 Seneca had not been observed since 1994.
