收藏资源简介:
JPL小行星数据库(SBDB)是一个包含所有已知小行星和彗星的完整目录,包含轨道元素、物理参数和发现元数据。该数据集由NASA喷气推进实验室的太阳系动力学小组维护,并随着新观测数据的加入而每日更新。数据集包括轨道元素(参考历元的开普勒轨道元素)、物理属性(绝对星等、直径、反照率、光谱类型等)和元数据(观测弧、观测数量、轨道不确定性)。它涵盖了编号和未编号的小行星、周期性和非周期性彗星。该数据集适用于表格分类和表格回归任务。
Complete catalog of all known asteroids and comets with orbital elements, physical parameters, and discovery metadata. Updated daily from NASA JPL. The JPL Small-Body Database (SBDB) is the authoritative source for orbital and physical data on all known asteroids, comets, and other small bodies. It is maintained by the Solar System Dynamics group at NASAs Jet Propulsion Laboratory and continuously updated as new observations refine orbit solutions and new objects are discovered. This dataset includes orbital elements (osculating Keplerian elements at a reference epoch), physical properties (absolute magnitude, diameter, albedo, spectral type where measured), and metadata (observation arc, number of observations, orbit uncertainty). It covers numbered and unnumbered asteroids, periodic and non-periodic comets. This dataset is suitable for tabular classification, tabular regression tasks.
