Tractor beam
From Tardis Wiki, the free Doctor Who reference
A tractor beam is a beam of energy projected from a vessel or device which can tether and pull another object. The Doctor's TARDIS has had the ability to create a tractor beam. The Doctor utilised his TARDIS' tractor beam to pull a neutron star away from Chloris, in the process burning out the tractor beam. (DW: The Creature from the Pit). It had been repaired by his tenth incarnation when he appeared to used it to save the Sanctuary Base 6 Rocket from a black hole. (DW: The Satan Pit)Y
