Talk:Atira asteroid

Risk
I'm going to be an ignorant blimp and ask:Can we experience an impact event by these stones?--CAN T 21:22, 26 April 2006 (UTC)
 * In theory, if one of the unknown Apoheles made a close approach to Venus, Venus could nudge the asteroid's orbit outwards making it an Earth-crossing asteroid. -- Kheider (talk) 15:02, 11 August 2015 (UTC)

Etymology
The claim that this is a Hawaiian word was added anonymously. It looks suspiciously like aphelion (< apo-helion). This is either a happy coincidence, or a hoax. Hopefully I'll be able to confirm / disconfirm soon - or does someone here know? kwami 05:48, 11 October 2007 (UTC)
 * According to David J. Tholen, it is really the hawaiian word for orbit : look here (better put a reference in the article). Duckysmokton 10:32, 11 October 2007 (UTC)
 * Thanks. David just confirmed that account himself. kwami 18:50, 11 October 2007 (UTC)
 * I put 'said to be the Hawaiian word for orbit' as I doubt an astronomical sense is the primary definition, even if used to translate English orbit in textbooks, and we don't know what that primary sense is. kwami 18:54, 11 October 2007 (UTC)

Apohele?
I have found no reliable website that describes "Apohele" asteroid class. But JPL NEO website names NEAs inside Earth's orbit as Atira asteroids. So, the article subject is Atira asteroids. — Chesnok (talk • contribs) 23:20, 4 March 2010 (UTC)

Oppositions
The article refers to "oppositions". Objects whose orbits lie within the Earth's orbit can't have oppositions - only inferior and superior conjunctions. What does the text mean? -- Chris C (talk) 13:30, 21 May 2013 (UTC)


 * Only 15 known objects (12 asteroids+Mercury+Venus+Sun) do not come to opposition. So in this case the term oppositions (Opps.) is probably loosely used to mean different epochs with maximum solar elongation since these objects seldom get more than 60 degrees from the Sun. -- Kheider (talk) 14:25, 21 May 2013 (UTC)
