离散盘
黄道离散天体 （scattered disc objects ）是在我们太阳系最远的区域（离散盘）内零星散布着，主要由冰组成的小行星，是范围更广阔的海王星外天体（trans-Neptunian objects（TNO））的一部分。离散盘最内侧的部分与柯伊伯带重叠，但它的外缘向外伸展并比一般的古柏带天体远离了黄道的上下方。

Scattered disc 离散盘
The scattered disc (or scattered disk) is a distant circumstellar disc in the Solar System that is sparsely populated by icy minor planets, a subset of the broader family of trans-Neptunian objects. The scattered-disc objects (SDOs) have orbital eccentricities ranging as high as 0.8, inclinations as high as 40°, and perihelia greater than 30 astronomical units (4.5×10 km; 2.8×10 mi). These extreme orbits are thought to be the result of gravitational "scattering" by the gas giants, and the objects continue to be subject to perturbation by the planet Neptune.
