TAU (spacecraft)

Index TAU (spacecraft)

TAU (Thousand Astronomical Units) was a proposed unmanned space probe that would go to a distance of one thousand astronomical units (1000 AU) from the Earth and Sun by NASA/JPL in 1987 using tested technology. [1]

Center of mass

In physics, the center of mass of a distribution of mass in space is the unique point where the weighted relative position of the distributed mass sums to zero, or the point where if a force is applied it moves in the direction of the force without rotating.
