A Likely Long-period Comet from the Inner Oort Cloud
We report the discovery of a minor planet (2006 SQ372) on an orbit with a perihelion of 24 AU and a semimajor axis of 796 AU. Dynamical simulations show that this is a transient orbit and is unstable on a timescale of ∼200 Myrs. Falling near the upper semimajor axis range of the scattered disk and the lower semimajor axis range of the Oort Cloud, previous membership in either class is possible....
متن کاملOort Cloud Formation and Dynamics
The Oort cloud is the primary source of the “nearly isotropic” comets, which include new and returning long-period comets and Halley-type comets. We focus on the following topics: (1) the orbital distribution of known comets and the cometary “fading” problem; (2) the population and mass of the Oort cloud, including the hypothetical inner Oort cloud; (3) the number of Oort cloud comets that surv...
متن کاملMOND orbits in the Oort cloud
We numerically investigate the features of typical orbits occurring in the Oort cloud (r ≈ 50 − 150 kAU) in the low-acceleration regime of the MOdified Newtonian Dynamics (MOND) taking into account the External Field Effect (EFE). We use three different forms of the MOND interpolating function μ(x) and two different values for the Galactic field at the Sun’s location. We find that MOND produces...
متن کاملImpact cratering and the Oort Cloud
We calculate the expected flux profile of comets into the planetary system from the Oort Cloud arising from Galactic tides and encounters with molecular clouds. We find that both periodic and sporadic bombardment episodes, with amplitudes an order of magnitude above background, occur on characteristic time-scales ∼25–35 Myr. Bombardment episodes occurring preferentially during spiral arm crossi...
متن کاملThe mass disruption of Oort cloud comets.
We have calculated the number of dormant, nearly isotropic Oort cloud comets in the solar system by (i) combining orbital distribution models with statistical models of dormant comet discoveries by well-defined surveys and (ii) comparing the model results to observations of a population of dormant comets. Dynamical models that assume that comets are not destroyed predict that we should have dis...
