揽瓜阁D91 柯伊伯带天体
>public knowns:
-mis of P, a planet since discovery
-less known: >70,000 orbit sun beyond N
>objects: found within a ring: KB
-KBOs
1.orbit N, survive from age (far from N)
2.inclinations – excited (by: 1.planetesimals 2.passing star 3.unknown means)
>passing: pass 100 ; rare but possible
-scattered KBOS:
1.large,eccentric orbits
-scattered effect: out of solar
-also:N -crosss orbits
0orbit sun: orbit N 2圈:3圈 时间 3:2
-same to P
-K belt smaller < was
Development of N: many KNOS blow
>still some large can be found
1.间接细节题:KBO [E]
定位第二段
E 感觉只有E再讲一个很罕见的现象发生
2.间接细节题:scattered KBOS 第三段[C/D]
A是same 把 B hold E感觉没有提及 D
C感觉同义改写
3.间接细节题: 问Pluto[A]
感觉A没有问题KBO = P
