摘要

在这项工作中，我们研究了太阳辐射压力（SRP）对改变小行星轨道以支持行星防御、科学研究或材料开发问题的影响。这种替代方案考虑了连接在小行星上的一个系留反射气球（或一组反射气球），其面积与质量比很高，以使用SRP偏转潜在危险的小行星（PHA）或使目标小行星接近地球。系绳被认为是不可伸展的，没有质量的，并且这种运动只在小行星绕太阳的轨道平面内描述。然后，该模型用于研究系链长度、反射率系数和面积质量比对小行星轨道偏差的影响。

ON THE EFFECTS OF SOLAR RADIATION PRESSURE ON THE DEVIATION OF ASTEROIDS

In this work, we study the effects of solar radiation pressure (SRP) on the problem of changing the orbit of an asteroid to support planetary defense, scientific research, or exploitation of materials. This alternative considers a tethered reflective balloon (or a set of reflective balloons) attached to the asteroid, with a high area-to-mass ratio, to use the SRP to deflect a potentially hazardous asteroid (PHA) or to approximate the target asteroid to Earth. The tether is assumed to be inextensible and massless, and the motion is described only in the orbital plane of the asteroid around the Sun. The model is then used to study the effects that the tether length, the reflectivity coefficient, and the area-to-mass ratio have on the deviation of the trajectory of the asteroid.
