Deimos was discovered by Asaph Hall, Sr. on August 12, 1877 at about 07:48 UTC (given in contemporary sources as "August 11 14:40"Washington mean time using the old astronomical convention of beginning a day at noon, so 12 hours must be added to get the actual local mean time).[6][7][8][9] Hall also discovered Phobos at the same time, after deliberately searching for Martian moons.
The names, originally spelled Phobus and Deimus, respectively, were suggested by Henry Madan (1838-1901), Science Master of Eton, from Book XV of the Iliad, where Ares (the Roman god Mars) summons Dread (Deimos) and Fear (Phobos).

Mars' moons, Phobos and Diemos, were discovered on August 18, 1877 by Asaph Hall working the telescope at the U. S. Naval Observatory in Washington. What Phobos and Deimos both are is almost certainly captured asteroids, in the view of astronomers today.
Both of Mars's moons, Phobos and Deimos, were discovered by American astronomer Asaph Hall in 1877.

Mars has two moons: Phobos and Deimos. The names mean "panic" and "terror."
Yes, Phobos is bigger than Deimos. Phobos mass is .00000018 and Deimos mass is .000000024. Phobos is 12X8 (miles) and Deimos is 7X6
