Gulliver's Travels or satellites, which revolve about Mars". This may have influenced Voltaire, whose 1750 story "Micromégas" also refers to two moons of Mars. In 1877, Asaph Hall discovered the two real moons of Mars, Deimos and Phobos; in 1973 craters on Deimos were named Swift and Voltaire, and from 2006 numerous features on Phobos were named after elements from "Gulliver's Travels", including Laputa Regio, Lagado Planitia, and several craters. The term "Lilliputian" has entered many languages as an adjective meaning "small and delicate". There is even a brand of small cigar called Lilliput. There is a series of collectable model houses
Transit of Phobos from Mars the autumnal equinox and the vernal equinox, while farther from the equator they happen closer to the winter solstice. Observers at high latitudes (but less than 70.4°) will see a noticeably smaller angular diameter for Phobos because they are considerably farther away from it than observers at Mars's equator. As a result, transits of Phobos for such observers will cover less of the Sun's disk. Because it orbits so close to Mars, Phobos cannot be seen north of 70.4°N or south of 70.4°S; observers at such latitudes will obviously not see transits, either.
