Barycentric orbit elements of K2 at the previous and subsequent perihelion for two considered solutions A1 and A0.
| Solution A1 | Solution A0 | |||
|---|---|---|---|---|
| Previous orbit | Subsequent orbit | Previous orbit | Subsequent orbit | |
| Perihelion distance [au] | 2.625 : 3.815 : 8.335 | 1.793346 ± 0.000056 | 2.264 : 3.041 : 6.391 | 1.793300 ± 0.000067 |
| Aphelion distance [103 au] | 34.22 : 41.45 : 52.44 | 1.752 ± 0.012 | 30.11 : 37.40 : 48.98 | 1.744 ± 0.016 |
| Inverse of the semimajor axis | 48.28 ± 7.91 | 1140.2 ± 8.0 | 53.48 ± 10.14 | 1145.4 ± 10.3 |
| Estimated time of perihelion passage [106 yr from now] | −4.22 : −2.97 : −2.26 | 0.03270 ± 0.00027 | −3.81 : −2.54 : −1.84 | 0.03252 ± 0.00035 |
| Percentage of dynamically old VCs (q < 10 au) | 97% | 100% | 97% | 100% |
Notes. Inverse semimajor axis values are in units of 10−6 au−1. Orbital elements are described either by a mean value (with a 1σ uncertainty) when a normal distribution is applicable, or otherwise by three deciles at 10, 50 (median), and 90%.
