Oct 6, 2020 at 6:18 | comment | added | David Hammen | @relayman357 If you want to call estimates that are accurate to parts per billion, if not parts per trillion, yes, you can call those "best guess" estimates. But that is a bit disparaging. | |
Oct 6, 2020 at 6:11 | comment | added | David Hammen | @AndrewSteane Not Newtonian mechanics. JPL uses a parameterized post-Newtonian (PPN) model of the solar system. In other words, it uses general relativity (better written: A somewhat simplified version of general relativity). | |

Oct 6, 2020 at 0:46 | comment | added | mmesser314 | Best estimate is a better say to say it than best guess. One can calculate the trajectory one would see if the known matter was all there is. Deviations from that trajectory can be used to estimate where unknown matter is and how it is moving. That improves our knowledge of the matter out there. A calculation based on the improved knowledge gives a better estimate of the true trajectory. We can continue the calculation beyond where we can see the spacecraft. | |

Oct 5, 2020 at 22:44 | comment | added | Andrew Steane | By using Newtonian mechanics, our best knowledge of the distribution of stuff inside and near the solar system, and the measurements of the trajectory when it could still be detected. | |
