There is normally no similarity between stars in a constellation or asterism other than the direction they are in relation to Earth. They are normally a collection of dimmer near by stars and brighter further away stars.
An example of this is the constellation Centaurus. AlphaCentauri is the closest star system to earth. It has 3 stars, Proxima Centauri which is about 4.2 light years and Alpha Centauri A and B that are 4.3 light years away.
On the other side Beta Centauri or Hadar is a bright star 350 light years away.
There are however examples where some or most of the stars are connected.
Take the asterism the big dipper or plough in the constellation Ursa Major. Merek (Beta Ursae Majoris), Phecda (Gamma Ursae Majoris), Megrez (Delta Ursae Majoris), Alioth (Epsilon Ursae Majoris) and Mizar (Zeta Ursae Majoris) all seem to be about the same distance from Earth (between 78 and 84 light years) and all seem to be moving in the same direction. They are known as the Ursa Major Moving Group.
Only Dubhe (Alpha Ursae Majoris) and Alkaid (Eta Ursae Majoris) do not seem to be connected.
What else can I help you with?
A group of stars that forms an imaginary picture is called what?
A constellation. (Also an asterism does this.)
What is a smaller group of stars within a constellation.?
It can be called a star cluster, an open cluster or an asterism.
The Big Dipper is an example of a?
An asterism, which is a grouping of stars that form a recognizable shape.
What is the difference between asterism and constellations?
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.
A is a smaller group of stars within a constellation?
A is a smaller group of stars within a constellation, typically forming a pattern or shape that is easily recognizable. They are formations that have been historically recognized and named due to their distinctive appearance in the night sky.
A group of stars such as the big dipper?
The Big Dipper is an asterism, not a constellation. An asterism is a recognizable group of stars within a larger constellation. The Big Dipper is part of the Ursa Major constellation and is commonly used for navigation due to its distinctive shape.
What is the difference between an asterism and a constellation?
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.
Is the big dipper a constellation or ans asterism?
The Big Dipper is both a constellation and an asterism. It is a part of the larger constellation Ursa Major, but it is also a distinct and recognizable pattern of stars within that constellation.
What do you call a small group of stars in a constellation?
A small group of stars that appear to be close together are often known a cluster. Technically its an asterism.
What is small group of stars that forms a pattern within a constellation?
An asterism.
What is a small group of stars that form a pattern within a constellation?
An asterism.
What is the difference between a constellation and an asterism?
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.
What is an imagined group of stars?
That would be a constellation. There are 88 recognized constellations. A subset of a constellation or other set of stars is called an asterism.
What are a group of stars that form an image?
The group is known as a constellation.
How is it possible to change asterism in a constellation?
You can pick any group of stars that seem to form a certain shape. That would be an asterism.
A group of stars that forms an imaginary picture is called what?
A constellation. (Also an asterism does this.)
Group of stars that forms a picture is?
That is called an ASTERISM. (For a somewhat related concept, see also: CONSTELLATION)
