What are the names of the seven stars that are found in a constellation and never fall?
The Pleiades star Cluster is also known as the "Seven Sisters" and it's found in the constellation Taurus (it's the "heart of the bull"). True stars never fall. Stars are gigantic balls of hot hydrogen and helium. The sun is a star. The other stars are vast distances away. The closest star other than the sun is over twenty five trillion (25,000,000,000,000) miles away. The so-called "falling stars" are actually meteors, very small bits of rock, usually only dust mites, which enter the earth's atmosphere at immense speeds, and burn up.
When seen from about 30 degrees north latitude, there are several constellations that "circumpolar" - they revolve around the North Star and never set. Two very distinctive constellations are Ursa Major (also known, variously, as the Big Dipper, the Great bear, and Charles' Wain) which contains seven bright stars and Cassiopeia (a.k.a. The Chair) which contains six bright stars. Ursa Major and Cassiopeia are extremely useful constellations; each is bright and distinctive, and right between them is the North Star, Polaris. In fact, if you draw a line between the two stars at the bowl of the Big Dipper, it points right toward Polaris. Polaris itself is nothing special; not all that bright, and pretty ordinary as stars go. But in the Northern hemisphere, Polaris is almost exactly north.
