Although the Moon is Earth's only natural satellite, there are a number of near-Earth objects (NEOs) with orbits that are in resonance with Earth. These have been called, inaccurately but provocatively, second, third or other moons of Earth. NEOs include quasi-satellites that orbit the Sun in resonance with Earth, which appear to orbit a point other than Earth itself, such as the orbital path of the NEO asteroid 3753 Cruithne.
Definition of CONVERGENCE. 1. : the act of converging and especially moving toward union or uniformity; especially: coordinated movement of the two eyes so that the image of a single point is formed on corresponding retinal areas.
On the one hand, convergence represents an expanding oppor-tunity for media conglomerates, since content that succeeds in one sectorcan expand its market reach across other platforms. On the other hand,convergence represents a risk, since most of these media fear a fragmen-tation or erosion of their markets.
