has herschel made any other discoveries?
He discovered two moons of Saturn, and Uranus. He also  measured the axial tilt of Mars and discovered that the martian ice caps changed size with that planet's seasons.
William Herschel
In his later career, Herschel discovered two moons of Saturn, Mimas and Enceladus; as well as two moons of Uranus, Titania and Oberon. He did not give these moons their names; they were named by his son John in 1847 and 1852, respectively, after his death. Herschel measured the axial tilt of Mars and discovered that the martian ice caps, first observed by Giovanni Domenico Cassini (1666) and Christiaan Huygens (1672), changed size with that planet's seasons
who discovered titania? William Herschel. which planet does it orbit? Uranus. how did it originate? It might have formed from an accretion disc or subnebula; a disc of gas and dust that either existed around Uranus for some time after its formation or was created by the giant impact that most likely gave Uranus its large obliquity. what is the atmosphere of the planet you mentioned? The outermost part of Uranus's gaseous envelope that is accessible to remote sensing is called its atmosphere. does it have moons? Yes, it has 27 known natural satellites. can you name some of them? The five main satellites are Miranda, Ariel, Umbriel, Titania, and Oberon.

William Herschel [SEP] Further discoveries
In his later career, Herschel discovered two moons of Saturn, Mimas and Enceladus; as well as two moons of Uranus, Titania and Oberon. He did not give these moons their names; they were named by his son John in 1847 and 1852, respectively, after his death. Herschel measured the axial tilt of Mars and discovered that the martian ice caps, first observed by Giovanni Domenico Cassini (1666) and Christiaan Huygens (1672), changed size with that planet's seasons. It has been suggested that Herschel discovered rings around Uranus. Herschel introduced but did not create the word "asteroid", meaning "star-like" (from the Greek "asteroeides", "aster" "star" + "-eidos" "form, shape"), in 1802 (shortly after Olbers discovered the second minor planet, 2 Pallas, in late March), to describe the star-like appearance of the small moons of the giant planets and of the minor planets; the planets all show discs, by comparison.
