✌✌Hey, mate here is your answer⤵
Mars has two natural satellites, which are its two moons named Phobos and Deimos. The two moons of Mars orbit its atmosphere, just as Earth's moon orbits this planet. The discovery of the two Mars satellites dates back to the late 1800s, owing thanks to astronomer Asaph Hall, who observed the two moons through a telescope at the United States Naval Observatory in Washington, D.C.
Phobos is about 22 km (14 mi) in diameter and Deimos is about 12 km (7.5 mi) in diameter.
Both satellites circle Mars at rapid rates; Phobos, the larger moon, follows an orbital path closer to Mars's surface. It completes an orbit around Mars in just seven hours, making three full orbits each day. Deimos exists farther from Mars and follows a longer orbital path, completing an orbit in 30 hours.
Because the orbit of Phobos is below synchronous altitude, the tidal forced from the planet Mars are gradually lowering its orbit. In about 50 million years, it could either crash into Mars's surface or break up into a ring structure around the planet.
The origin of the two moons is not well understood. Their low albedo and carbonaceous chondrite composition have been noted as similar to asteroids, supporting the asteroid capture theory. The unstable orbit of Phobos would seem to point towards a relatively recent capture. However, both moons have circular orbits near the equator, which is unusual for captured objects. Accretion early in the history of Mars is plausible, but would not account for a composition resembling asteroids rather than Mars itself, if that is confirmed.

Here is your answer ⤵⤵⤵
The two moons of Mars are Phobos and Deimos. Both were discovered by Asaph Hall in August 1877 and are named after the Greek mythological twin characters Phobos (panic/fear) and Deimos (terror/dread) who accompanied their father Ares into battle.
