Use of "Oort Cloud" in opening paragraph edit
Saying that any comet is an "Oort Cloud" comet overstates that comet's case: as Wikipedia's own article on the hypothesized Oort cloud states in its opening paragraph, "the Oort cloud ... is a theoretical spherical cloud of predominantly icy planetesimals believed to surround the Sun ....". The language of the article at hand needs to be changed to reflect the fact that the Oort cloud is, at this point, only theoretical - insufficient proof of its existence and measurements of its nature have been obtained; perhaps "long-period comet" would be more appropriate. 108.68.36.7 (talk) 13:41, 13 December 2015 (UTC)
- The Oort Cloud is an accepted Scientific theory. C/2013 US10 took millions of years to get to the inner Solar System. There is no reason to change the language as this is not an article about the Oort cloud. Long-period comet should be used for object with aphelion less than ~1500AU, not objects with aphelion at ~47,000AU. -- Kheider (talk) 14:36, 13 December 2015 (UTC)
Why does it have two tails? edit
I came to find out and was disappointed an answer was not present. I'll look about for an answer to add. --Pmsyyz (talk) 12:38, 7 March 2016 (UTC)
- Almost all comets display an ion gas tail and a dust tail. Viewing geometry makes some comet tails more interesting than others. -- Kheider (talk) 15:55, 7 March 2016 (UTC)
Update edit
Some of this should be changed to past tense... --Mortense (talk) 20:51, 16 May 2017 (UTC)
