Constellations doesn't take the same shape forever, as over time, the stars that make up the shape start to move away from each other.
Over billions of years, maybe.
Constellations are patterns of stars in the sky, if the constellations disappeared then all the stars would disappear, and there would be virtually no astronomy. :(
They're generally named for the constellation they appear to originate from. For example, the Leonids appear to radiate from a location in the constellation Leo, and the Perseids from a location in the constellation Perseus.

Stars and constellations appear to move in the night sky because the Earth is rotating, while the stars and constellations stay there.

Earth revolves around the sun. That is why the constellations we see from Earth appear to change.
The Earth's rotation causes the constellations in the night sky to appear to move across the horizon. This rotation causes the constellations to rise and set at different times throughout the year, leading to different constellations being visible during different seasons. Additionally, the Earth's atmosphere can cause the stars to twinkle and appear less bright or crisp, depending on factors such as air pollution or atmospheric conditions.
Change form: yes. Appear and disappear: no.
when did the Mojave apear and when they disappear
No. Constellations are arrangements of stars that appear to form pictures.

As earth orbits the sun, different constellations come into view while others disappear. Circumpolar constellations are visible all year long, other constellations are not.

disappear
The base word for "disappear" is "appear."
