Created Talk-Page[edit]

Created talk-page for "2016 HO3" article - Enjoy! :) Drbogdan (talk) 03:03, 16 June 2016 (UTC)[reply]

All the external links to JPL_Small-Body_Database are broken — Preceding unsigned comment added by Leonbloy (talk • contribs) 17:13, 27 June 2016 (UTC)[reply]

Fixed broken JPL links by adding the |id=469219 to the JPL small body template. --Fomeister (talk) 02:43, 7 July 2016 (UTC)[reply]

Title causing issues[edit]

The title of this page resulted in all links generated by the JPL small body template to be broken. Though I was able to correct the link by adding the |id=469219 to the template, why is the (469219) in the title at all? Non of the other quasi-satellite, or asteroid for that matter, put the id in there.

Requesting another editor to discuss.Fomeister (talk) 02:58, 7 July 2016 (UTC)[reply]

Most other quasi-satellites and such NEOs don't have enough observational data on them to adequately determine their orbit. We were fortunate with this one, in that PanSTARRS was able to find precovery images back to 2011, which in turn allowed me to find precovery images to 2004. Numerous other objects such as (357439) 2004 BL86, (33342) 1998 WT24, and (85989) 1999 JD6 all follow a similar numbered-unnamed scheme which has worked so far. The number is in the title to refer to the object's full designation, in a similar manner that you wouldn't refer to 1 Ceres as 1801 AA, or (15760) 1992 QB1 as 1992 QB1. exoplanetaryscience (talk) 05:52, 7 July 2016 (UTC)[reply]

Thank you exoplanetaryscience for your time. I completely understand the use of the identifier (SDK-ID) for others, was just trying to fix the broken links. So are you okay with the using the id| pipe so that the external links work now? Fomeister (talk) 06:01, 7 July 2016 (UTC)[reply]

I see no problem with it myself. Thank you for noticing the issue, by the way! exoplanetaryscience (talk) 23:49, 7 July 2016 (UTC)[reply]

Weight[edit]

Hi. I guess it will pretty difficult to determine this object's size, even though someone have already published an estimate apparently (weird). But how much does it weigh? That should be fairly easy to calculate, if its trajectory and speed is known. Does anybody know anything? RhinoMind (talk) 13:40, 29 January 2017 (UTC)[reply]

Compared to the Sun and Earth it is a massless particle. The mass is easily lost in the uncertainties. -- Kheider (talk) 05:51, 19 November 2017 (UTC)[reply]

The mass can be estimated from its diameter (~41m) and a density (3000kg/m^3??), perhaps around 108,000,000 kg? Its trajectory or speed says nothing about its mass. The mass would obviously be important if it was on collision course with the earth. I see the Chelyabinsk meteor was perhaps 20m in diameter, so about 1/8th as much mass. Tom Ruen (talk) 06:00, 19 November 2017 (UTC)[reply]

and the diameter was estimated using the apparent brightness and an assumed albedo ? so its just a guessimate ? - Rod57 (talk) 10:41, 23 December 2017 (UTC)[reply]

Appearance and shape[edit]

Presumably we have no way to tell how much of the lightcurve variation is due to non-spherical shape vs variations in surface albedo. Could any current telescope (or radar) 'see' even the orientation of its axis of rotation ? - Rod57 (talk) 10:52, 23 December 2017 (UTC)[reply]

Have any sources published lightcurve plots (maybe with error bars) - Rod57 (talk) 11:07, 23 December 2017 (UTC)[reply]

Pronunciation[edit]

Can someone provide an IPA pronunciation for the name Kamoʻoalewa? I'd appreciate it! Nrco0e (talk) 03:24, 9 May 2019 (UTC)[reply]
