Moving a World

[robject]

Planetary Gravitic Harness. Size 9 (40M tons), TCr 80, TL 23.

A gravitic "belt", encircling a world at medium orbit, which changes the potential energy of a planet, shifting its orbital distance from the primary. This device requires power equal to that from a planetary core tap.

Harnesses such as these are used in the construction of a Rosette, for example.

Strong practical experience in orbital system mechanics is required to properly and safely modify the orbits of planets.

There is already one example of what you are discussing in the Traveller canon. It is in JTAS No. 2, the article on Victoria/Lanth.

Attempting to move the pieces, or to alter their positions will generally not work; an explosion or fusion gunfire may do somethng, but will also destroy the display. If, however, any of the four orange asteroids are touched, they will easily move, although they cannot be shifted beyond the edges of the dais. When moved, each is replaced by a holographic image in its original location. As time passes, the holographic image will move to the location of the orange asteroid. And, detector data will show (if the adventurers look) that the real body corresponding to the mote is also moving within the Victoria system. If a mote is placed near a world, it will assume orbit; if placed on a world surface, the mote will cling to the model world, and the real asteroid will impact in that location.

It would appear that in the Victoria/Lanth, system, several such devices already exist.
