Wild theory[edit]

I've come across a weird theory telling that the Boethin comet is the same object as the WD5 asteroid. However, the only source I found is this article. So it is certainly a hoax, be warned. Kromsson (talk) 14:46, 25 December 2007 (UTC)[reply]

Comet Boethin never broke up![edit]

Citation from http://www.spacedaily.com/reports/NASA_Sends_Spacecraft_On_Mission_To_Comet_Hartley_2_999.html

"Scientists theorize comet Boethin may have broken up into pieces too small for detection."

I am experienced amateur astronomer strongly interested in comets. Comet 85P was observed on 1975 and 1986 apparitions and was not observed in 1997 and (yet) 2008 apparitions [1] [2]. I know that comet Boethin never broke up! We could lose it because of non-gravitational forces [?] or non-stable brightness. There was no attempts to recover this comet on 1997 because it was almost exactly behind the Sun [3]. On 2008 there was few (negative) attempts to recover it (down to 25 mag) [4].

Therefore, I delete the citation. — Chesnok (talk) 08:40, 26 December 2007 (UTC)[reply]

That's interesting, but Yahoo groups are not a reliable source. Even if you had a reliable source that states this point of view, we should include both hypotheses, to satisfy encyclopedic breadth. --Dhartung | Talk 22:51, 12 January 2008 (UTC)[reply]

The New York Times is not a reliable source. At Yahoo groups, there is many competent astronomers but Henry Fountain is not an astronomer. — Chesnok (talk) 08:02, 14 January 2008 (UTC)[reply]

I have found the source of this statement. It is strange that I haven't heard about it until now. This unsuccesful attempt to observe 85P and estimation of possible 85P remnants was not widely known among amateur astronomers. — Chesnok (talk) 16:50, 6 May 2008 (UTC)[reply]
