It was discovered on 4 January 1989, by Australian astronomer Robert McNaught at the Siding Spring Observatory in New South Wales, Australia.[12] It is named after Bobbie Vaile.[3] Orbit and classificationBobbievaile is a stony, non-family asteroid from the main belt's background population. It orbits the Sun in the inner main-belt at a distance of 2.0–2.9 AU once every 3 years and 10 months (1,397 days). Its orbit has an eccentricity of 0.18 and an inclination of 12° with respect to the ecliptic.It was first observed as {{mp|1979 PF}} at El Leoncito in 1979, extending the body's observation arc by 10 years prior to its official discovery observation at Siding Spring.[12] Binary asteroidOn 7 May 2009, it was announced that Bobbievaile was determined to be a binary asteroid based on a series of lightcurve observations. Bobbievaile (the primary) is estimated to have a diameter of {{val|8.02|0.02|u=km}}, and its minor-planet moon (the secondary) to have a diameter of approximately 4.57 km.[5] The primary is probably spherical. NamingThis minor planet was named in memory of Australian astrophysicist Roberta Anne "Bobbie" Vaile (1959–1996), lecturer at Western Sydney University. She was a SETI enthusiast and participated in both the establishment of the SETI Australia Centre and the conduction of Project Phoenix.[3] The official naming citation was published by the Minor Planet Center on 22 April 1997 ({{small|M.P.C. 29671}}).[18] References1. ^1 2 3 {{cite book |title = Dictionary of Minor Planet Names – (6708) Bobbievaile |last = Schmadel | first = Lutz D. |publisher = Springer Berlin Heidelberg |page = 551 |date = 2007 |isbn = 978-3-540-00238-3 |doi = 10.1007/978-3-540-29925-7_6048 |chapter = (6708) Bobbievaile }} [1][2][3][4][5][6]2. ^1 2 {{cite web |title = 6708 Bobbievaile (1989 AA5) |work = Minor Planet Center |url = http://www.minorplanetcenter.net/db_search/show_object?object_id=6708 |accessdate = 13 March 2017}} 3. ^1 {{cite web |title = MPC/MPO/MPS Archive |work = Minor Planet Center |url = http://www.minorplanetcenter.net/iau/ECS/MPCArchive/MPCArchive_TBL.html |accessdate = 13 March 2017}} 4. ^1 2 {{cite web|last1=Johnston|first1=Robert|title=(6708) Bobbievaile|url=http://www.johnstonsarchive.net/astro/astmoons/am-06708.html|website=johnstonsarchive.net|accessdate=29 May 2015}} 5. ^1 2 {{cite journal |display-authors = 6 |first1 = Joseph R. |last1 = Masiero |first2 = T. |last2 = Grav |first3 = A.
