摘要

提出了一种求解与黄道面有很小倾角的初始轨道的算法。作者提出的方法是基于求解一个三变量超越方程组。利用单纯形的Nelder-Mead方法寻找目标函数的最小值，从而得到系统的解。以255,447 （2005 YN24）小行星为例，给出了其轨道的确定结果。

Determination of the Preliminary Orbit in the Coplanar Case

An algorithm for finding a solution to determine a preliminary orbit with a very small inclination to the ecliptic plane is proposed. The method proposed by the author is based on solving a system of transcendental equations for three variables. Solutions to the system are found by searching for the minima of the objective function using the Nelder–Mead method for a simplex. As an example, the results of determining the orbit of asteroid 255 447 (2005 YN24) are given.

期刊介绍： Solar System Research publishes articles concerning the bodies of the Solar System, i.e., planets and their satellites, asteroids, comets, meteoric substances, and cosmic dust. The articles consider physics, dynamics and composition of these bodies, and techniques of their exploration. The journal addresses the problems of comparative planetology, physics of the planetary atmospheres and interiors, cosmochemistry, as well as planetary plasma environment and heliosphere, specifically those related to solar-planetary interactions. Attention is paid to studies of exoplanets and complex problems of the origin and evolution of planetary systems including the solar system, based on the results of astronomical observations, laboratory studies of meteorites, relevant theoretical approaches and mathematical modeling. Alongside with the original results of experimental and theoretical studies, the journal publishes scientific reviews in the field of planetary exploration, and notes on observational results.
