Help with 2008 EA9
[edit]2008 EA9 is an Apollo asteroid orbiting within the region accessible to a crewed NEO-visiting spacecraft. http://www.lpi.usra.edu/sbag/meetings/sbag2/presentations/PlymouthRockasteroidmission.pdf JPL gives 2008 EA9 a cumulative impact probability of 2.9e-05 over 11 potential impacts. http://neo.jpl.nasa.gov/risk/2008ea9.html I believe this is sufficient to make the notability of 2008 EA9 within Wikipedia guidelines for an article. Could someone familiar with asteroid articles please create one for this object? (sdsds - talk) 22:20, 4 July 2010 (UTC)
I'm not a number, I'm a planetoid
[edit]I understand the calendar method of naming, but how are the "final" desingations arrived at? That is, why does, frex, 3200 Phaethon have that precise number? (That the name is chosen by the discoverer, I get.) I'd say this would be very worthwhile adding... TREKphiler any time you're ready, Uhura 10:02, 14 October 2011 (UTC)
- Near-Earth asteroids are not numbered until they have been observed at two or more oppositions. See: How Are Minor Planets Named? -- Kheider (talk) 22:44, 25 February 2014 (UTC)
Links to articles about using Apollos as Earth/Mars ferries
[edit]I wonder if any consideration has been given to using Apollo bodies as ferries between Mars and Earth. Any links to such musings, articles, etc. would be greatly appreciated. Vivafelis (talk) 01:59, 20 June 2019 (UTC)
- The energy required to match velocity with an asteroid headed near Mars will be the same as just going to Mars, but now you would require an extra landing and launch. -- Kheider (talk) 07:39, 20 June 2019 (UTC)
- Unless of course you get in front of it and wait for it to hit you. —Tamfang (talk) 01:28, 6 July 2023 (UTC)
Chelyabinsk mention in intro
[edit]Hello all, including @Smeagol 17: I made a couple copyedits just now, and did some quick searching re the number injured and whether they were all injured by flying glass, as it now reads. I don't think the latter part is correct, and the number injured conflicts with both Chelyabinsk#2013_meteor, Chelyabinsk_meteor, and the USA Today article given in the source. I don't have time to address all this, but wanted to share what I noticed with others who might want to take a look. A couple sources I found in a hasty search: RT World News article, USA Today article. Eric talk 23:37, 20 January 2020 (UTC) (talk) 06:28, 21 January 2020 (UTC)
- 1615 injured : https://www.1obl.ru/news/o-lyudyakh/roditeli-zastrakhovali-syna-za-den/ Most were hit by glas, but some by other debris. (can't now find about the later) Smeagol 17 (talk) 06:31, 21 January 2020 (UTC)

off-center
[edit]The diagram implies that the aphelia of these bodies are mostly on one side of the zodiac. Is that so? —Tamfang (talk) 01:30, 6 July 2023 (UTC)
