Citation of Value

Value use Citation of http://www.asterank.com/. This is a database that lists the subject of the article. There is no direct link to Ryugu. A wikipedia user using the citation would need to search within the Asterank database to find the particular asteroid. As it happens the asteroid is currently the top of the list. — Preceding unsigned comment added by Sallen2006 (talk • contribs) 18:43, 11 July 2016 (UTC)[reply]

Spacecraft probe droid is nearing the asteroid: June 6th-11th

Astrophysicist Jonathan McDowell of the Smithsonian Center for Astrophysics is reporting daily on the closing approach of Hayubusa to the asteroid Ryugu.

Hayabusa/Ryugu closing distance reports. Slow closure rate from 2200 km away on 6 June to 1400 km on 10 June. Cheers. N2e (talk) 20:45, 11 June 2018 (UTC)[reply]

Additional info from JAXA

This Fact Sheet by JAXA also describes the asteroid (starting at page 104). Perhaps a more knowledgeable editor can mine additional data from it: [1]. -Cheers, Rowan Forest (talk) 16:57, 4 October 2018 (UTC)[reply]

Near Earth just got closter

Science News reports in sept 14 p.11 that the astroid lacks "dust" commonly found on the surface. this suggests that, not only did it fly close in the past, but that it may have skipped off earth's atmosphere in the last few thousand years.

also, if the thing orbits the sun every 16 months, then it should have hit the earth about 2000 times in the last billion years. — Preceding unsigned comment added by 72.94.231.11 (talk) 21:52, 25 September 2019 (UTC)[reply]

Surface Gravity

Just noticed a rather odd description of the asteroids surface gravity as 1/80,000 that of Earth. It sources this from an external article. Just did the calculation myself from the numbers in the article and the equatorial surface gravity comes out as about 1.2 x 10^-4 m/s^2.

From this the 1/80,000 figure is roughly correct at 9.5 m/s^2 but is imprecise. But it is a non standard way of describing surface gravity by referencing it to Earth.. This is not really OR since anybody can do the calculation.. 87.74.208.91 (talk) 09:30, 2 May 2024 (UTC)[reply]
