This is a very good question - the difference between an asterism and constellation is this: a constellation is a pattern of stars that identifies a complete object, animal or character. An asterism is a pattern of stars that is NOT a constellation.
There are 88 "official" constellations recognized by the International Astronomical Union. There are hundreds of additional star patterns that aren't "official"; these are called "asterisms". For example, the Big Dipper isn't one of the IAU's official constellations; it is part of the constellation "Ursa Major". So the Big Dipper is an asterism.
An asterism, which is a grouping of stars that form a recognizable shape.
Most of the (northern) constellations we use today were invented in ancient times, especially by the ancient Greeks. More recently, a few were added (to fill the entire surface of the sky with constellations), and the limits between constellations were defined exactly.
Does the question mean the distance between two stars? It does change, but very slowly on a human time scale. In 100,000 years most of the familiar constellations will look quite different.
The constellations that are commonly used for navigation to determine direction include the Big Dipper (part of Ursa Major), the North Star (Polaris), and Orion. These constellations are visible in the night sky and can help to determine north or south, east or west.

The term for an unofficial constellation is "asterism." These are recognizable star patterns that are not part of the recognized 88 official constellations.
The word "asterism" is given to a grouping of stars that is not on the "official" list of 88 constellations maintained by the International Astronomical Union. Also - an asterism is PART of a constellation - like Orion's Belt, The Big Dipper, or a pattern made from the stars of other constellations, like The Summer Triangle, etc.
No, The Big Bear is a constellation, not an asterism. Constellations are officially recognized patterns of stars, while asterisms are informal groupings of stars within constellations that form recognizable shapes. The Big Bear is known as Ursa Major in astronomy.
An asterism is a smaller group of stars within a constellation, while a constellation is a larger pattern of stars that form a recognizable shape or figure in the night sky.
It is called a constellation.Constellations.Technically an asterism, but most people usually call it a constellation.
That would be a constellation. There are 88 recognized constellations. A subset of a constellation or other set of stars is called an asterism.
The Big Dipper, Little Dipper, Northern Cross, and Orion's Belt are all asterisms. They're recognizable patterns that are parts of constellations but not complete constellations.
The word "asterism" is used to refer to a pattern or grouping of stars that is not on the International Astronomical Union's list of constellations. But an Asterism IS NOT a constellation - it can be a pattern like the Big Dipper (which is part of the constellation Ursa Major, the Great Bear), Orion's Belt, The Summer Triangle, etc.
A constellation is a group of stars that form a recognizable pattern in the sky, often representing a mythological figure or object. An asterism is a smaller, unofficial grouping of stars within a constellation that forms a distinct shape or pattern.
Coma Berenices is a constellation near the Constellation of Leo. Historically it was an asterism (arrangement of stars), but is now one of the 88 constellations covering the night sky.
We use the word "asterism" for a grouping of stars that isn't one of the 88 "official" constellations recognized by the International Astronomical Union, the IAU. The most famous asterism is the central part of Ursa Major; we call it the "big dipper".
