| Abstract | |
This work aims to find an alternative solution to the important problem of deflecting asteroids that are coming too close to Earth, with the risk of collision. This alternative is based on the use of a device with a large area/mass ratio attached by a tether to use solar radiation pressure (SRP) to help to deflect the trajectory of the asteroid. The paper describes the dynamics of the system composed by the asteroid, the tether and the device. The model is then used to study the effects that the tether length and the solar radiation pressure (acting on the surface of the device) exert on the deflection of a larger Potentially Hazardous Asteroid (PHA). As a starting point, the tether is assumed to be inextensible and massless and the motion is described only in the plane of the orbit of the PHA around the Sun. (AU) | |
