Do we have any info on how the orbit changed?
editDo we have enough observational data to know how the orbit of 2020 QG changed from it's close encounter with Earth?
The article just shows standard orbital ephemeris for a single Apollo asteroid orbit. But it would seem that, at 2900 km, the asteroid may have gotten a gravity assist / perturbation in the close encounter, and the new orbital parameters would have changed, perhaps markedly.
Would improve the article to reflect on this, if we have verifiable information. N2e (talk) 21:55, 17 August 2020 (UTC)
- The change in orbit is fairly small given how close the approach was. The orbital period was reduced from 990 days to 964 days. Both 2011 CQ1 and 2019 UN13 had more notable changes in perihelion/aphelion/period. -- Kheider (talk) 23:25, 17 August 2020 (UTC)
