The 1:2 resonance appears to be an edge beyond which few objects are known. It is not clear whether it is actually the outer edge of the classical belt or just the beginning of a broad gap. Objects have been detected at the 2:5 resonance at roughly 55 AU, well outside the classical belt; however, predictions of a large number of bodies in classical orbits between these resonances have not been verified through observation.
Earlier models of the Kuiper belt had suggested that the number of large objects would increase by a factor of two beyond 50 AU; so this sudden drastic falloff, known as the "Kuiper cliff", was completely unexpected, and its cause, to date, is unknown. Bernstein and Trilling et al. have found evidence that the rapid decline in objects of 100 km (62 mi) or more in radius beyond 50 AU is real, and not due to observational bias. Possible explanations include that material at that distance is too scarce or too scattered to accrete into large objects, or that subsequent processes removed or destroyed those which did form. Patryk Lykawka of Kobe University has claimed that the gravitational attraction of an unseen large planetary object, perhaps the size of Earth or Mars, might be responsible
tik tā nav 4X lielāka par zemi, bet tapatās kkāds ķermenis jau ir
+ tā var būt vnk varbūtība.
varbūt kāds ko vairāk pa šo zin??
Toltek, reku ir aizķēriens, mācies!!
Atradi kur? Linku luudzu. Paldies.
