concise?[edit]

The timing of the fly-by meant that the asteroid was illuminated by the sun from the perspective of the spacecraft, making the transmitted images clear and concise.

That last word seems inappropriate. Does concise have a special meaning in astronomy or photography? —Tamfang (talk) 18:55, 2 October 2008 (UTC)[reply]

Not that I've ever heard. Probably a poor choice of wording. CFLeon (talk) 17:32, 9 July 2010 (UTC)[reply]

"Survived impact"?[edit]

Has anyone suggested that maybe the big impact DID fracture a larger parent body? Some materials carry shock through and fracture at the antipodes. This is the reason for chaotic terrain on Mercury, for instance. Note that the 'sharp edges' do seem to be on the opposite hemisphere from the giant crater.

Nomenclature[edit]

Is the following sentence in quotes acceptable? It's based on this list. "Except for the montes of Mercury and the lunar maria, the craters of Steins are the only features in the solar system whose names are not derived from proper nouns."--Cam (talk) 00:59, 1 June 2012 (UTC)[reply]

At least, there's also Alpha Regio on Venus. —Tamfang (talk) 08:04, 20 May 2017 (UTC)[reply]

On Mars (off the top of my head): Margaritifer (pearl-bearing), ~~Chryse (gold), Argyre (silver)~~, Noctis (of night), Syrtis Major (great bay); not sure whether to count Lacus Solis (lake of the Sun). —Tamfang (talk) 21:49, 25 May 2017 (UTC)[reply]

Oops, Chryse and Argyre. — Classical albedo features on Mars lists a few more. Aromatum (of fragrant spices), Aurorae (of dawn), Clepsydra (water-clock), Famae (of fame), Feronia (of wild beasts), Hesperia (evening), Juventae (of youth), Thaumasia (wonderful) —Tamfang (talk) 08:13, 26 May 2017 (UTC)[reply]

They may be almost unique among features named after the IAU adopted its scheme of themes. Triton has a few: Awib Dorsa ('rain'), Sipapu Planitia, Monad Regio. —Tamfang (talk) 03:45, 28 May 2017 (UTC)[reply]

Any estimate of mass[edit]

Did the flyby affect Rosetta enough to allow an estimate of mass ? - Rod57 (talk) 00:21, 13 August 2014 (UTC) -No, the frequency shift of the radio carrier signal was, as expected, below any measurable limit. --178.3.164.86 (talk) 16:50, 29 August 2015 (UTC)[reply]

mean diameter[edit]

the asteroid has dimensions of 6.67 × 5.81 × 4.47 km, which equates to a mean diameter of 5.3 km.

But the cube root of the product of the three diameters given is 5.6 km ... —Tamfang (talk) 08:06, 20 May 2017 (UTC)[reply]

Reversion[edit]

I don't understand why my edit was reverted. It makes the article more correct. Plenty of natural features on Earth are not named after proper nouns e.g. the Pacific Ocean. Grassynoel (talk) 09:19, 21 March 2018 (UTC) Grassynoel (talk) 09:19, 21 March 2018 (UTC)[reply]
