Limtoc is animpact crater on the surface ofMars's moonPhobos.[1] The crater, the diameter of which is 2 kilometers, is located within the larger and better-knownStickney crater.[1] Limtoc was officially named by theInternational Astronomical Union on 29 November 2006, after a character fromJonathan Swift's 1726 satirical novelGulliver's Travels.[1]
Limtoc is estimated to have formed within the last 109 million years, making it one of the youngest features on Phobos.[2] When the Limtoc impactor collided with Phobos, it created a significant amount ofejecta which was sent towards the northern edge of Stickney, where it collided with that crater's rim. Ejecta sent towards the southern edge was largely catapulted out of Stickney.[3] This ejecta partially contributed to the formation of the blue spectral coloration seen on the south-western edge of the Stickney crater, along with the ejecta from Stickney itself.[2]
